I didn't read the rest of the thread just the initial post, so I'm sorry if this is repeated.
If you are looking at the Carribean check out Aruba.
Aruba is a desert Island just off of South America - the temperature in the summer is averages 82 degrees (about the same in the winter). Also, it's well south of the Hurricane belt so you won't have to worry about some storm coming through and ruining your honeymoon.
My wife and I went there in 2001 for our honeymoon and we could not have asked for a better trip. We didn't do all inclusive - we stayed at the Bucuti Beach Resort and paid for everthing seperately. That worked out pretty well, we spent less, but of course we didn't splurge on food and drinks like we would have in an all-inlcusive.
Crime (despite the recent national story) is EXTREMELY low in Aruba. We drove around and walked through the small towns, through Oranjested and never felt unsafe.
Do a little research on Aruba - you won't be disappointed. It has some of the best beaches, reefs (for scuba or snorkleing), great food, great landscape. Perfect place for a relaxed vacation!
