Strange rumors about Belize being anti-American...
I just chartered in Belize out of Ambrigis Cay this past March. Natives were very friendlier - far more so than the BVI. No problems or even close. i was told that crimes against tourists were severly punished. I will return ASAP. These people obviously knew who was buttering their bread.
Word is that Belize City is another matter and should be avoided. If you must stay overnight there - go to the best hotels.
