i did that exact same cruise for christmas of '07.
i did a snorkle catamaran in belize, then just went to the shops right where you get of the tender. since it was just my mom and i we didn't want to go to far into the island by ourselves. the snorkling was ok, but i didn't see much variety, just a few brown fish & some coral.
in cozumel i swam with the dolphins at Chakkanaab (sp?) which was amazing. there was also a ton of other stuff to do there besides just swim wih the dolphins. you could easily spend a whole day there.
