2 snorkel nuts want serious cay reef time back in Belize! Have plans for rainforest stay in the works, so now working on the 2nd half of the trip: 7 nites on a cayo w/ awesome snorkeling. We've narrowed selects to either Turneffe Lodge or Blackbird Caye resort on Turneffe OR Isla Marisol on Glover's. Lo maintenance mature adults, we do prefer quiet (no kids) when possible. We enjoy in-shore fishing, kyaking, sunset sails, self-guided "house reef" snorkeling and are also adept deep-water snorkelers who are used to jumping on the dive boat some mornings (one of us is a diver for 30 yrs.) All 3 lodges appear at parity per prices and amenities. Any suggestions on which island or resort may suit us best?
