For Diving: Maldives, Bonaire, Palau - Tahiti - All fabulous. Cozumel is good for a close dive destination. They are much more intent on protecting the reef there than in Belize. Don't know how it fared after the hurricane, though.
Aruba - never again. "One happy island" - NOT! We call it A-RUDE-a! Nice beaches, though.
St. John is nice. Don't like St. Thomas or St. Maarten.
Alaska B4 U Die! for sure!
Just to name a few.
