I'm from singapore. I dunno where exactly is my relative hse in vancouver island, but will try to visit the places u mention.
We'll be staying in burnaby most of the time. The places that I would like to visit are rockies and lake louise, maybe calgary too. Are these places all on the same way?
Can u recommend a car renting company with good rates?
First of all, you can easily visit Lake Louise since it is on the way to Banff after Golden. Calgary is also only about a 1.5 hour drive from Calgary as well.
On the Island, I forgot to mention the other most important tourist location which is Victoria. Depending where your relatives live, you can take the ferry which goes to Victoria from Vancouver. The other option is the Nanaimo ferry but the Victoria one is much nicer and more scenic because you pass by some of the Gulf Islands. They both take around 1.5 hours. If you can avoid taking a vehicle across on the ferry, it will be significantly cheaper.
As for renting a car, I did a quick check on Budget Car Rental and it looks like 7 days in April for a car rented in Vancouver will be about $250 but after taxes and other options (child seats etc.) it could be as much as +$350. You will need a credit card to rent a vehicle and you should check if your card will give you automatic extra coverage for car rentals so you don't have to pay twice. You should also be able to check rates if you Google Hertz Car Rental and National Car Rental.
There is also much you can do around Burnaby and the Lower Mainland as well including visiting Stanley Park, Grouse Mountain and the Capilano Suspension Bridge.
I am sure you will have a wonderful trip!
