Most resorts supply 24hr electricity, but some remote bungalows still use their own generators, which may be shut off at certain times, if that's not convenient for you, better double check before booking.
Prices can change with the season. Peak seasons are from December to March and July to August. Then and during special Thai holidays like Songkran, the island be can actually booked out. Securing the room of your choice as early as possible can be crucial for a satisfying holiday experience.
