Would like to share my experience at the St. Regis Bahia Beach in short.
property is superb. very unique. private (good for the frum community). beach is 2 miles long, all private, so you can comfortably take a stroll without bumping into many ppl. the hotel has only about 140 rooms in 12 separate "casa's" or buildings, only 3 floors tall at most.
staff was great. you really get driven around in a golf cart every time you wanna go somewhere. we did it many times a day, and they did it every time gladly.
rooms have extra large fridge, so we were there for 4 days, and were able to store all our food in the fridge. - the food from chabad is very far and would cost like $80 just to taxi it over. we froze meat and milk and stayed good for our flight from NY. also worth it to stop off and stock up on fresh food and water at Ralph's around the corner from the hotel.
we were there during hurricane Irene this summer, but we still had a great experience. got upgraded to a beautiful suite after the hurricane. but even before that the regular room was very spacious with a separate kitchen room.
the hotel is only a half hour from the rain forest which seems to be the only major attraction IMHO. otherwise the hotel can really keep you entertained for your whole stay. between biking, gulfing, tennis, boating etc.
anyhow, that's it for now. for more info please reply or PM me. I'll be glad to help.
