Great activity and must-do experience. Went with my sister, we're in our early 60s and not great swimmers. Customer service was excellent. We got lost in the dark getting to the meeting point. The 730p boat waited as long as they could but had to leave without us. We stayed in communication with the reservationist and she kindly put us on the next departure at 9p (there were 22 total participants, mostly young adults). The Hang Loose tour includes snorkel mask/tube, wetsuit tops, life vests, pool noodles to keep your feet up and snacks afterwards. Make sure to bring your own towel. Didn't use it, but the main deck bathroom seemed fairly clean and spacious.
