Not sure if it is that easy! There is no schedule that I could see on Tropic Ferry website, and with the price of fuel for such a long trip I doubt they are going back and forth for each arriving flight. So who is to say that you wont have to wait for transport? As well, it isnt a smooth road to the Tropic Ferry , so depending on the seas and weather, you could, after getting up at a crazy hour , getting to your local airport,flight to Belize etc., then be bumped around to the ferry departure , bumped around for an hour and a half to the island on a boat for about the same price as the 15 min Tropic flight?? Seems to me the sort of option I would only consider if it saved me some big dollars. But that is me.
