#9 Be sure to book your boat ticket off Koh Phangan in advance, the boats get very full and you could end up stranded for a few extra days
????? Is that some sort of tourist equivalent of the KSR rip off tourist buses? The car ferries from Thon Sala are not bookable, and I doubt that they would ever be "too full".
Believe it or not, the FMP is completely irrelevant to the vast majority of the people that live on KPN, and they live lives that do not revolve around a bunch of puking adolescents, including going from and coming to the island.
