We didn’t have anyone in the group with glasses on. Maybe they put on their lens for it. I think you would need to do the same too because the mask they give you is not “glasses friendly :/

We did not go out on a boat. We swam out to turtle town. It wasn't a bad swim at all. Very nice actually as you are buoyant in the water. They do provide a life jacket if needed.

We didnt go out too far but it was definitely far enough to see an octopus. Shelby even grabbed it and tried bringing it to us so that we could see it. It was great! As far as sharks go, she did tell us that the tour before us did see a shark. It was a white tip shark that was hanging out with the turtles. She told us not to freak out if we see it because he is not interested in us. I did not see it but I believe my kids saw him come out for a quick second from the cove. Overall it was an amazing experience! I loved it so much that I wanted to go again the next day but we already had other activities planned so we couldn't. I do highly recommend and can't wait to come back and do it again.

When we went we were mostly 8-10ish feet above the bottom. So you do need to be able to swim or have on a life vest. It was super cool though!

You swim. They obviously provide flippers and a snorkel, and life jackets are available if you'd like. The instructor also tows a paddle board along, so you can grab a hold of that if you need a rest from swimming. Hope that helps.

I am not sure if there is an age limit. I would call the destination place.
