We used to get the bus (it was mental, exactly as you would expect with chickens and goats and kids hanging on the the roof rack!!) to Cancun for weekends when I lived in Belize nearly 30 years ago - a lot has changed, as we went back about 10 years ago. It was just a small fishing village that was "invaded" by the American tourist industry, and I was lucky to be there just before it became as commercial as it is these days.
Have a great break - you deserve it! But do go to see the pyramids......
Steels, did you get to visit Tikal in Guatemala while in Central America ? Amazing place
