Hi Taylor!
I guess one question that would help you is, what are your priorities? Do you want a place on the caribbean with blue water and powdery white sand? A place close to ruins? (Mayan area), do youy guests like fishing? (Cabo and Puerto Vallarta), attracted to any culture? (Cuba, Mexico, Jamaica) What kind of side activities do you see you and your guests doing while at your wedding location?
Welcome aboard and happy planning!
