There is no tour guide on this tour, as the captain will show you the different spots and stay on the boat. The local Thai captain of the boat speaks very basic English, just enough to communicate about the tour. If donations are asked during the temple visits, this is not mandatory but of course allowed if you want. Entrance fees on the other hand are mandatory and need to be paid in cash. Rain in Thailand is unpredictable and can happen anytime. The tour will continue in the rain if conditions are safe, and no refund will be granted. If conditions are determined to be unsafe, the tour will be canceled and you can reschedule or get a full refund. Make sure you are dressed properly by temple standards to visit the temples . That is, no bare shoulders, no bare knees.
