We are sailing on the Carnival Glory 9/11/04 and am requesting information on shore excursions for Costa Maya, Progresso, Belize and Cozumel. We are considering doing our own thing in Costa Maya and Cozumel - any suggestions? In Belize, we have narrowed it down to either the Shark Ray Alley Adventure or the Horseshoe Reef Snorkel, which one would be best? The Chicken Itza Ruins sound interesting in Progresso but is it worth a two hour ride on a bus? Any suggestions for things to do would be appreicated.
