I personally would never get in the ocean at night, without trained supervision. I am a very strong swimmer. Especially with children I would not consider it. I did the Fairwinds manta snorkel tour, and it is very much worth it. Adventure of a lifetime, so yes, I would do it, but only with a good tour company. Fairwinds goes from the marina by the Sheraton. It was a mad house out there, and I cannot imagine not having the gear that they provide. There were people in their own boats running into other people, trying to follow us and use our gear, etc. It can be very disorienting at night on the ocean, especially if the swells are up. Plus they know how to attract the Manta's, with lights, etc.
