Where Should We Honeymoon?

I do realize that this is typically the groom's responsibility to plan, but let me tell you, the word typically does not apply to the life of a medical student and his fiance!  So, as my groom-to-be is currently preoccupied with books, books, more books, and a cadavear, the brainstorming has been left to yours truly! 

Therefore, I'm channelling all my sources and wondering if anyone has any fabulous honeymoon destinations to recommend?

Requirements:

1. Tropical, perferably Caribbean.
2. Somewhere we have never been before. {This nixes the Bahamas, the Keys, Costa Rica, and the Bitter End Yacht Club in the BVIs.}
3. Relatively easy travel. . . aka no Hawaiian 2 day travel time + 6 hr time difference.  I don't mind hopping on a plane and then a ferry, however.

Visualizing something very relaxing and serene. . .   Maybe a day or two, we'll hike or have a water activity while we are there, the remaining days just be able to relax by the beach or {private, preferably} pool with a book in hand.

Perhaps views like these. . .

This post has taken me forever to write because I keep getting distracted at GORGEOUS pics from the internet and daydreaming about the day we get to go to these places!

So tell me- where did you and your husband go?  Or if you are not married, have you gone to an incredible spot with your family or friends that would also be a great honeymoon destination?  I've heard rumbling of Turks and Caicos and St. Barts, but I don't know where to start!!
