Well, you can find here everything - peace on the beach, parties in the evenings, reasonable prices ($1,5 for beer, $1 for a coconut) and the locals serve great food (lobster, for example!). You can escape from noisy reality - there are no TVs here, neither wi-fi and so on. Definiteley worth going for 2 or 3 days!
The island is quite tiny, beaches are not crowded (20-30 travellers at one time only), the sea is clear. What to want more?
