Loved it down there, you will too.
That sounds great, their own Island!
I did a family trip, and arranged to put my hands on a kayak for some fishing. Inside of the reef the water is up to 30 ft - is all smaller stuff. Still fun. Outside/deeper are the biggn's - some grouper in the right time of the year on deeper under water cliffs. I never ventured pass the surf breaking on the coral reef. Wind can be gnarly, keep an eye. Shallow lagoons will have tarpon, bunch of bonefish, other stuff too.
Belize is a fun place to go visit. I'd go back.
