August is the busiest month for Caye Caulker, for the number of people on the island. In August it is a popular destination for Italians, so bring a tent if you dont have reservations, and be prepared for a sand mattress. You could get lucky, or.... not.

I would take my chances on finding a place if I were you. There are lots of places to stay! If you feel more secure making a reservation, make sure that you don't pay for your entire stay, you may be surprised at what you see when you get here vs. what you are actually renting and at what price! If it's only a deposit, that place is secure that you will want to stay, if it's no refund, be careful!!!
