Last year we went all around the island and to Bacala Chica, through the Mayan cut and did 3 snorkel stops. It was amazing and I fulfilled my life long dream of swimming with a manatee in the wild. She was about 2000 bls and just kept swimming around us. Also, saw a 600 lb sea turtle. We had a lunch that the captain and crew fixed on a beach which was delicious. An amazing day.
I'd highly recommend it. Searious Adventures is who arranged it for us. I believe it was $85 a person. Fabulous day! Just take plenty of bug spray cause the mosquitos are awful up that way.
