You need to be 17 years old to drive a vehicle in Belize, by law. Otherwise they will be totally safe as long as you keep them out of the popular night spots, I would say past midnight. Reggae & rum can be a bit too much to handle for a 16 year old. Besides the drinking age is 18. But besides that, they should have a serious blast with the cave tubing, zip lining, snorkeling, maya sites, etc...
