If anyone is looking for an incredible, adventurous, beautiful experience I would recommend going to Belize. DH and I just got back from a 10 day honeymoon there and we can't imagine anything more perfect. First we stayed at Ka'ana, a resort in San Ignacio which is on the mainland. We had 5 days of incredible adventures - exploring Mayan ruins, cave tubing, zip lining and canoeing through ancient caves. All of these were private tours and Ka'ana provided the most amazing service, food and romantic experience I can imagine. After that we spent the next 5 days at Victoria House on Ambergris Caye. It was a perfect beach paradise and a nice way to relax after all the Indiana Jones adventures we had been having. It's a beautiful country and the people are friendly and welcoming. English is the main language and most places take US currency. If you're still looking for a honeymoon spot definitely check it out - especially Ka'ana!
