My hubby and I stopped in Caye Caulker last year, and honestly, were a bit disappointed. The trees were down, from Hurrican Mitch, I believe, so it was VERY hot with not much shade. Also, it just seemed like more of a college kids, party town. We much preferred Ambergris Caye. It just depends on what you're looking for. I think Caye caulker is a bit cheaper, though.
