I am not really sure about the condos in Grand Cayman. We stayed at a place called Coconut Harbor which were laid out like a studio (but not nearly as nice). They cater to divers there. The Caymans are great if you love to scuba dive, but there is not much else to do as far as sightseeing. The water and the beaches are beautiful if you are interested in a beach vacation. The shopping is good but is very expensive. When we were there the rate of exchange was 80 cents to the dollar. All prices were in Cayman dollars so if you were paying $20 for a meal you were actually paying $24 American. If you have to go during the summer accomodations will be cheaper. Good luck. If you have other questions, maybe I can answer them for you.
