We went on this trip as two families with 4 kids ages 10, 12, and 15 and it was a truly amazing once in a lifetime experience for us all. Getting into the ocean at night is an intimidating experience, but Simon and his crew explained everything clearly and even the youngest of our group did just fine. As stronger swimmers we were on the far end of the board and they had a crew member there who explained what we were seeing and letting us know facts about the manta rays. We saw about 20 before heading in after 45 minutes and they get so close! I read comments that people got cold on this tour. We were provided with a wetsuit jacket and I found I was just fine. The kids started to get cold at the end but also made it the whole time. If you are prepared to be a bit chilly for the experience, it isnāt an issue.
