We did the St John mini boat adventure. It was awesome, really fun, BUT it is true that it is IMPOSSIBLY DIFFICULT to get back into the boat after the snorkeling. As I recall, it was easy enough for DS13 and oh so tough for me! I'm not athletic, and I'm not skinny. I don't remember if it was hard for everyone else. I would do it again, but only if DH came with to help me hoist myself back into the boat. This is definitely a trip for the physically fit. Also, since DH wasn't with (he doesn't like the water!) I had to drive the boat. A larg-ish rubber boat with a motor, that's fine..but to see over the bow, you have to ride ON YOUR KNEES, kneeling on a wood plank. Ouch! the vibration of the boat hitting the waves, slamming my knees onto that board...ouch! And you have no choice because you have to keep your boat in line with the others and match the lead pace. However, this trip was one of the most exciting exhilirating things I've ever done! The coral reef we snorkeled above was FANTASTIC, mesmerizing, incredible. Like a Discovery Channel movie. So if you have help, go for it. Maybe start doing pull ups now?

There is also a bit of walking involved. Not a problem, but the day we went the guide was in a hurry and the pace was brisk. Fun but a true challenge.
