          Historical Traveler Reviews Tranquility Bay Beach House Resort Marathon

          Excellent bed and clean


          We stayed in a 3 bed unit Jan 7-14. Pro's-super comfortable bed, clean, nice views, excellent pool (heated), great kitchen, tv, etc. Con's master bathroom small and 3rd bedroom small-3rd bed no dresser. Everybody 6 adults were pleased.

          Great Accomodation


          We booked a 4 night special at Tranquility in December 05. We had a two bedroom villa at$199 a night. The accomodation is great, nicely furnished with some nice touches (Plasma TV, DVD Players etc). Still some teething troubles as it's so new, and there is still quite a lot of building work going on. Much of the resort was not finished, but we had everything we needed. The pool was all done, and was fantastic.

          Marathon Key was disappointing, no doubt partly due to the effects of Wilma, but there just wasn't enough there for us. On our last visit to the Keys we stayed ay Key West - and wish we had done so again. There's no way we would have got accomodation of this quality at this price, so overall we were pleased with the choice.

          New Luxury Resort


          Anyone who has visited the Florida Keys, usually do not equate them with the words "luxury resort" . However, having just returned, we found the most beautiful, elegant new resort for anyone wishing such a place on the Keys. It is called Tranquility Bay, and is very much Key West architecture. The MBR has french doors which open out onto a wonderful balcony overlooking the fantastic pool and luxurious white sand beach (I'm afraid the sand was most probably trucked in). Restaurant opening this weekend...tiki bar on beach soon...rooms have full kitchen with granite counters and stainless appliances...2 or 3 BR units available. We did not stay here...just visited and got info on purchasing a unit...but it is outstandingly beautiful if you want the relaxation of the keys, while staying in beautiful surroundings.

          WOW!! What a great experience


          Just returned back from the florida keys. I usually stay in islamarada but this time I ventured down to marathon to try out this new resort tranquility bay. good-bye islamarada. this place is great,still not complete but even in this unfinished condition it is far superiour to any other resort in the keys, and i have stayed in most of them. The check-in was great and all the staff was very friendly. we rented kyacks and enjoyed the fabulous beach,yes a beach in the keys with real sand and a swimming area. the pool was great and relaxing. see ya'l at tranquility bay

          Be very cautious!


          My wife and I stayed at Tranquility for exactly 16 hours! When we arrived, we were shocked to find that the place was still very much under construction. You're not going to get much peace and quiet there unless you can do so through the noise of hammers pounding and circular saws buzzing throughout the day. There is no restaurant or bar on site and there is not even a vending machine! And don't try to complain to the front office -- there is no front office, moreover, there are no phones from which you could even call the front office (if there was a front office). Their advertising crows about free high speed wireless internet connections throughout the resort. When I inquired about the wireless internet, a staff person deceptively told me that she "didn't think that my unit was set up for the wireless internet yet." In fact she, knew, as I subsequently found out, that there was no wireless internet on site.

          The courtyard and common areas were littered with construction debris. There was no pathway from our unit to the pool area. The beautiful white sandy beach that is depicted in their literature and on-line is not the beach that you will find on site when you arrive.

          The $500 deposit policy is ridiculous! I was double charged ($1,000) for the deposit and it was not refunded within ten days after checkout, as promised! In fact, when I called to inquire about the double charge, I was told that I should have been charged $1,500 because I had booked a three room unit! I was shocked because their literature indicates that the deposit is for the number of units reserved not the number of bedrooms in the unit! After some arguing, I got them to relent on that ridiculous claim. After several calls and ignored FAXES, I finally got them to refund my $1000 but is was one big, unnecessary, and inconvenient pain in the neck to get them to refund my $1000.

          In fairness to Tranquility, my 16 hour stay commenced some two weeks after Hurricane Wilma hit the Keys and there was a great deal of damage to the whole area. But my gripe stems from the fact that I called several times before I departed for the Keys and asked them if they were fully operational. I was assured that everything at Tranquility was up and running. Those representations simply were not true.

          If they had simply been honest with me, I would have deferred my trip to a later date. As it turned out, we spent 16 hours there and then had to hustle to find another place to stay while we attempted to re-book our airline flights back home. They didn't offer an apology, an explanation or any type of recompense at all. It left a very bad taste in my mouth and ruined a much anticipated and very expensive trip to the Keys.

          I would be very cautious about booking a trip to Tranquility. Although the rooms are beautiful, their customer service skills need much improvement. At the prices they are charging, you have a right to expect much more from them. Maybe things will improve with time. Until they do, I would look elsewhere.

          Lovely place if only it were finished


          Me my wife and 2 young children stayed here for 2 weeks Dec 9th to 22nd.My first time to Florida i wasnt sure what to expect.I loved the drive from Miami to Marathon the most enjoyable 2 1/2 hour drive ive ever had.When we arrived at Tranquility Bay i was surprised to be accosted by a Jamaican fella in the car park!! This turned out to be the check in area as the reception wasnt ready.I was put into the beach lawn house that i booked but i asked to be moved as soon as we got in there as there was all building work going on outside.We were accordingly moved to poolside house No 9 which was perfect 5 seconds walk from the pool and the beach with great views.The houses themselves were wonderfull almost brand new very classy big comfy beds and a real home from home.The pool was also great especially for young kids.The beach was the biggest dissapointment i expected some kind of Caribbean white shelving sand clear blue water paradise but instead got what felt like builders sand murky water and a swimming beach i wouldnt let my dog swim in full of sea weed.On the other hand i loved to sit down on the lagoon and fish which i did almost everyday it was really peacefull as no one went on to the beach as it wasnt finished either.The real draw back for me was no bar or restaurant, for $250 a night that was scandalous. There were no facilties at all apart from movie rental.All in all i really enjoyed myself there but it would have been 5 times better with a restaurant,bar and finished clean swimming beach.I also think its very expensive at over $250 a night including taxes and fees (especially when you stay 13 nights almost $3500 !!!)Amazing that this is the half price cut rate!When it changes to $500 a night i cant imagine who would stay there unless some major changes took place then people with deep pockets only need to bother.Contrary to other reports i found the staff very friendly and helpfull especially Garfield (Jamaican fella in the car park} Erika,Kim and Pete the manager.The bottom line is when its finished it will be lovely and i would love to go back but at the rate i just payed not the new one.

          Tranquility bay 'beautiful'


          stayed here week of 17th, our family rented three homes..ours were in the pool section and the other two were in the lawn area..


          Landscaping is almost complete, beautiful lagoon style pool..stay here or the beach were very new and clean, top of the line appliances, and lot's of kitchen supplys and laundry soap inc (small packages)ocean views are stunning and you can see it from all top balcony's..try the resort's sport rentals very nice service..


          no restaurant or tiki bar open, kids club and spa still not fully open, bathrooms small (but o.k) lawm area not complete and homes there beware work on construction starts at 7.30am my family were furthest away and still was distube by it!!!

          staff were not that great but o.k..the housekeepers and maintaince were very good..the place needs to have more taylor service but i guess it will come when it's totally a great rate and for same rate would 100% visit again but at the asking price of $500+ may consider the caribbean..

          weather was good but last two days were a little cool..but expected for time of year..all in all loved the tranquility bay..better in some way that 'hawks cay' but not accoeding to my kids (hawks cay has way way more for younger kids)

          Very nice, but worth the money?


          We spent our honeymoon (7 Dec-10 Dec) at Tranquility Bay and over all give it an above average rating. We arrived quite late and were upgraded to a 3 bedroom beachfront house, although we had booked a 2 bedroom beachfront house. The houses are very beautiful and rather well equipped. The plasma tv in the lounge was great and we were even able to watch our wedding DVD!

          The woman who came to our house to "check us in", as the reception was still not complete was very nice - however, that's the last we ever saw of her. The bathrooms were serviced daily with fresh towels and the rubbish was emptied. The bedding was changed after 3 days. That is however, the only service that is provided. They are so far behind schedule that the phone system was still not in. Very frustrating! And whilst the restaurant and bar were far from being complete there wasn't even a drinks vending machine in site. Their $500 security deposit is ridiculous. They take that off your credit card immediately upon arrival and say that they will return the money to you within 10 days. In fact as there was NO mention of this deposit when I booked (nor on the confirmation letter received from the resort) they promised to "audit" the house the night of our departure and said we would be refunded the money within 2 or 3 days. It's now 10 days since we checked out and they still have my money!

          The "beach" leaves a lot to be desired. Perhaps once all of the construction is complete it will be nicer, however the sand was full of building rubble and the tiki hut was still a construction site. I can't imagine that the swimming beach will ever be suitable for swimming. On a positive note, the pool is absolutely gorgeous and we spent quite a bit of time in it!

          I think if you were lucky enough to get reservations during their "promotional" period it would almost be worth the cost. However, prices will almost double in the new year and then there will be the added cost of the bar and restaurant. I don't mind paying for luxury but for that kind of money I expect to be pampered! Would I go back? Not without some considerable incentive.

          Wonderful stay at Tranquility Bay!!


          Tranquility Bay is very beautiful - we loved our beach house and the pool. The swim beach was fun for wading and sand castles but not really for swimming. We went to Bahia Honda beach and found it much better for enjoying ocean play with the kids. The resort pool was warm and the landscaping was complete on the pool side.

          We had unit #7 and it was quiet and well done. We could see the ocean from our kitchen. The beds and bedding were also very nice.

          I highly recommend!!

          One word of caution, the restaurant, bar and activities center are not open yet.

As much as I love climbing lighthouses, with the heat of the day I didn't have the energy this time.

One of the kids from next door and I walked around the building and looked around but didn't see anything. The hydro guy was here in about a half hour.. by himself. Hmm. We didn't think that was very safe, but he did get the power on. We've been taking it easy since ...
