Chris..we don't dive or snorkel,but I am sure that you can find plenty to do while the guys are diving.We veg,swim,sun,walk the beach,eat,etc.,and not in that order.Where are you staying? We have never stayed on the north end of the island,but know you have to take a water taxi to town,but that is no big deal.We rented a golf cart for the week and were very glad we did..went everywhere, even tho it is a small island,my husband had a bad hip and could not do much walking,so we were able to go everywhere.There are lots of stores for buying or browsing,and so many places to eat! You will not have a problem finding something to do,take my word for it. Where do you live? 150 inches of snow! You must be ready for AC!Belize it!
