Oh sure you can, I have never been on a cruise, have always thought I woulnt like it much, I am not big on eating, seems like not enough time to be in one place, alot of time schedules etc. but I would think 5 hours on Caye Caulker would be a wonderful experience to take home, lots of locals to talk to at the Split, on the streets. You probably wont get a sense of the community here, but what do you get in a bus of 100 ship mates going to Old Belize, or to Ceasars, The Mayan Ruins are cool,but Id still choose 5 hours on Caye Caulker.
