If you're looking to stay on Caye Caulker and dont want to be in the middle of everything do yourself a favor and stay with Luciana in the small oasis she has made on the south end of the island. I stayed there for 4 nights and it was an overall great experience. The only unfortunate downside was that the south end of the island lost power twice in the first two days (not Luciana's fault I may add) but she more than made up for it by offering a discount for my duration there. She also offered great advice for different bars/restaurants/activities to do around the island!
