Tropic Air now emails their tickets, so it is easy to get one. I don't have their email address in the states with me, but I do have it in my office. So, if you want to email me tomorrow at firstname.lastname@example.org I can give it to you. Courntey is the contact in the states and she probably doesn't know anything about reservations made in Belize, but you could try. I wouldn't worry too much. If there is not a reservation for you, and you have to pay twice, I would think the hotel would reimburse you. There are flights out of international to San Pedro about every 30- 60 minutes.
