I'll admit to it, I'm a born and raised Coloradan, and now I like to call Ambergris Caye my home. (well I lived there for 2 years so why not?) From Denver, you can usually get some good flight deals either with travelocity.com or also Belize-Airtravel.com It's a company out of Ft. Collins. Great guys up there to help you plan your trip, even on a moment's notice.
