Wendy, they do provide snorkeling equipment.

Kathy, I will email them to see if they can send somebody to the ship to pick us up and if so what the charge would be. Even if they can't, I know that Hertz has a seven passenger van that we can share and I can pick it up right across from the pier at the Sheraton. With tax it is only $85. I'm a pretty good driver in spite of them taking my license away! LOL As to the time, we board the boat at the Puerto Del Rey Marina in Fajardo, which is about an hour away, so we would need to leave about 9am and should be back around 6pm.
