hi-ho. i was there august 2000. i understand things had changed a lot since then, due to the hurricanes, but i will tell you what i know.
the staff was terrific. fun to chat with. the beach is beautiful and private. the view incredible. they offer free kayaks & sunfish.
i thought the food there was pretty good, but limited in menu and $$. our only complaints then were that it was very hot to eat outdoors (air conditioning would have been a welcome treat), and the flies were always on your food. there was open seating only, and it was august. screening would have helped. i can't say i had a bad meal tho, and different dinner menus daily. i recommend the paella. good drinks.
there is an cozy & interesting but also pricey restaurant next door, rendezvouz. they serve upscale french-thai, and it was wonderful. nice decor too.
the dive operation seemed top-notch. i watched steve, the divemaster, certify a parapelegic while i was there (among others), and i thought he was very professional. frank did 9 dives with them and had no complaints. they were very nice, too.
the rooms were ok, nothing special. comfortable in a minimalist way. we had a beachfront cabana that badly needed updating, but i think they did that last year.
