My girlfriend and I are planning a trip to the Caribbean in July, together have been to the Caymans and St. Martin and she has been to Barbados on her own a few times..we're trying to decide which island to try this time? we love to hang out on gorgeous white sand beaches, snorkel, read a book in a hammock with a fruity cocktail, great local cuisine etc..of the islands I listed in the subject box can anybody make some recommendations on the best island for us to visit in July? (keep in mind she has already been to Barbados and we've beeen to St. Martin but really enjoyed it) I'm going to be using miles to fly there and those are the 4 best options that work with our travel dates. Should we try a new island or go back to one we've already been to? I appreciate any advise one of you Caribbean experts would like to give!
