Thanks for the advice! We ended up getting a cabin in the middle of the ship. We definitely didn't want to pay the extra money for the balcony suite. Our cruise is less then a month away and we're very excited!

I've done multiple cruises with Carnival, staying near the bottom (i.e. 1st and 2nd decs) and I've been completely happy (then again I didn't want to pay twice as much, as you get charged more on Carnival for the higher decks), but I've never cruised through a bad storm (thankfully).
I'd say cabin selection depends on what you're looking for, as prices range from $500+ for interior cabins to $3000+ for balony suites on the same cruise. When I cruise, I'm hardly ever in my room, so I don't mind an interior cabin, whereas I have friends who shell out the extra $1000 because they wouldn't dream of cruising without having their own balcony.
To respond to your last question, Cozumel is a fun place to explore and you can easily grab a cab to a beach when you're at the port. The last time I was there, however, I had sun poisoning from laying out the day before in Belize, so I took it easy and walked around the markets in town and did a lot of shopping/drinking.
