I am not sure I am the right source for this cause I would be biased hehe.. anyhoo if you have the money, choose a resort run by larger international hotel chain also don't come in the rainy season (now its rainy). As for the reasons, its quite, the beaches are nice, and if you are a diver, underwater reefs are worth a visit in some areas and if you ain't a diver, you could always get a ride in a submarine (make sure the water is not murky). Most of the resorts are pretty well designed and comfy and private, I suggest a water bungalow (with glass on the floor hehe) and some resorts have underwater restaurents n SPAs. Last but not least, one of the telcos do provide a data plan only SIM for your N900 and most of the resorts have WiFi everywhere.
