Depends if you are holidaying to dive or if you want something else while you are there? If you want something else try looking at some of the cayes around southern Belize, a complete undiscovered gem that has spectacular diving (ever heard of the Blue Hole!!!) off great walls just 10 mins by boat and inland stuff that will blow your mind - Mayan ruins, big cats and caves that just have to be seen to be believed. I spent 10 days at Thatch Caye off the coast from Dangriga over Christmas and was stunned by the area. The staff were fantastic and the diving was just us on the boat and no other dive boat on the water, truly special in this day and age of mass production diving....
