I have looked through the forums and can't find recent answers to these questions.
I know that one gets from one part of the island to another by hopping a "taxi boat" (or longtail?). And I understand they are pretty easy to find. How much is it per person, generally? (Not talking about chartering for a day, just to hop a boat to get somewhere else)?
Besides that expense, what else will I need cash handy for? Most restaurants (I assume?) take plastic -- or should I have cash for everything?
