Activities, food, taxis etc are much more expensive than normal prices, an not even better. You should for instance rent motorbike just outside the resort, on the left, its twice cheaper!
A 3 star resort pretending to be a 4 star... Overpriced in terms of accommodation, food and especially service, but with an excellent location for a peaceful holiday.
Rent a motorbike at the resort. It's very cheap and it will get you to the best beaches on the island: Lo Paa Raet and Tiikut, where you'd be most probably all alone.
