Here's a web site for ideas. We stayed at Holiday Hotel in 1998, our first time to Belize (Ambergris Caye). It was in town, close to everything, one room, no TV or pool, but clean. The second time we stayed at Playador now known as Exotic Caye's Hotel. They have nice cabanas, pool and nice beach. It's about 1/4 mile from town (within walking distance). We've made eight trips in all. Since then we bought a condo at Belize Yacht Club, but rent it out year round to a nice couple who live there, so we stay at another unit. It's quite there, a small pool but no real beach. Ramon's is nice with a good size beach. Banana Beach or Sunbreeze Hotel are also good choices.

Then there is Caye Caulker, which is years behind Ambergris Caye. Very laid back small island village. Caye Caulker, Belize - Vacation Travel Information <http://www.belize-vacation.com/caye-caulker/caye-caulker.htm
