Here is a link to some places on Ambergris Caye, Belize. We spent most of our time at Fido's Courtyard and Pier. Good food cheap drink and good people.

As far as Plya. Wow the sky is the limit. Any kind of liesure sport, adventure trips, history excursions. Click on the Trip Planning tab at the top of the page. Playa has a very Bohiemian feel. Kind of hippie trendie. Nice mix of people from all over the world not all American like Cancun. It makes for a nicer time. Mostley people in late 20's and above. You'll see the 60 year old keeping right up with the 30 years olds. Just very diverse. Very safe. Great food, music. People tend to dress up a little in the evening and get out of their shorts (except some American's and it's usually their 1st day)

And you'll find the occational Minnesotan wearing socks with their sandles.
