HOT but there's no changing the climate! :) we had a lovely time and our guide was helpful, informative, and had a lot of pictures, hands-on examples, and even showed us personal things like his wife's birth certificate that gave a truly unique look into the mayan culture.
beautiful, professional and well informed. the guide took time to have a personal conversation with every guest on the boat. he took time to find a map and show us how to get to a specialty shop we asked about. the reef was a god 'first time' reef, and had lots of fish.
