River Shark - I have flown Mayan and Tropic several times and felt very comfortable and safe on both. But I will pack my snorkel gear in my daypack!
The flight to AC is soooo cool. You can actually see fish in the water.
The look on my daughters face when she saw the 4 seater that took us to Caye Caulker was priceless! She sat next to the pilot and within 30 seconds was trying to hang out the window for a better view and yelling back to me to look at everything...
