Where is the best place to go in December?

Where is the best place to go in December?

I am planning a 3 week holiday in December. I want to go somewhere hot where we can dive, relax and see some wildlife in it's natural habitat. Does anyone have any suggestions/recommendations? Many Thanks

Question about Cook Islands

Have a look at this article: http://www.worldreviewer.com/holiday-weather-guide/wheres-hot-in-december Hopefully there's lots of suggestions there.

Belize has amazing diving and it's great in December. Or Thailand's Andaman Sea?
