Hi Sha,
Welcome!
The section you have posted in is primarily for the San Pedro/Ambergris Caye section of Belize...its the most popular tourist area, and is a wonderful place to visit.
My suggestion to you is to ask yourself....."if I were visiting England would I go to Stonehenge, or the Moors, or would I be more likely to enjoy a coastal resort (but with bright blue ocean and lots of sun!)
Look at the entire board, and you will see info on the Mayan Ruins, the Rain Forest of the interior, and some of the less popular areas.
Ambergris Caye is more like a Caribbean country that caters to western tourists in its own delightful way, whereas the remainder of the country, with a very few exceptions is far more "Central American"
Whatever your taste for adventure, you will be able to find it in Belize, but do not try and fit in too many areas, as intra country travel is relatively expensive
Enjoy your trip!
