Hey Nicki, your friend should have no problem just hopping on a flight to San Pedro. My friend and I were there last week, and when we got to Belize City, we had reserved but not paid for two seats on Tropic Air, but the line was not moving thanks to some man who could not chill out and had to cause problems. My friend and I were anxious to get to the island and noticed the Maya Island Air counter had noone waiting in line, so she walked over and asked if we could buy a ticket to get to the island and it was no problem. We bought two tickets, and were on our way in 10 minutes tops. We let the people know at Tropic Air they could give up our two seats and we left. The line had still not moved when we left thanks to the disagreeable man at the counter. The planes from Tropic Air and Maya Island leave so frequently, that there really is no problem with not having a reservation. Hope you all have a great trip. I am so jealous. Enjoy.
