We went on this excursion in early November, and liked it a lot. The equipment was first rate, the crew was a lot of fun and very competent. They gave a nice "snorkeling 101" class for the newbies. Our grandkids and thei parents had never snorkeled before, but they felt comfortable jumping in and had a great time.
Everyone got a pirate tattoo on the way back, and the kids thought that was fun. We got to raise the sails, and each of the kids got to steer for a while on the return trip.
Beer and "banana benders" were readily available, and they made sure your glass was never empty. Judging by the amount of Doubloon souvenirs that DW purchased, she must have enjoyed the trip a lot. Or enjoyed the banana benders a lot.
The only negatives were that it was filled to capacity, and that made for a pretty full boat. The other thing is that the "snack" provided was simply chips and salsa. We didn't care, but some people thought they'd get a real meal.
They also take everybody's picture and post them on their website. Here's DW and I, and doesn't it look like we're having fun?
