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.
There is no schedule because they are responding to reservations and demands on a particular date. That's why they ask you to contact them for information.
They do not go back and forth with each flight and sometimes there is a wait. The folks at Tropic Ferry can tell you what to expect if you contact them with your flight info.
There is no "bumped around" from the international airport to the Oar House - it's a simple 3 or 4 minute drive in a proper van. The boat can be rough or not - but it's a big one, and the ride can be pretty comfy if weather is fairly normal.
For those who arrive at San Pedro airport and then have to take yet another mode of transport to their hotel, it can be nice to consider an arrival right at the dock of your hotel. IN particular for resorts and homes well outside the town core, this can actually save time.
Agree on the price issue - it's a bit high. Further, the flight is sooooo beautiful.
There are those who don't like to fly in little planes and for them this alternative is a no-brainer. Glad that we all have a choice!
