You can definitely hire a guide to take you privately to snorkel . Is it that you want to experience these things as a family? If so ...Capt. Bicho from fishingsanpedro.com can make a wonderful day of fishing/snorkeling combo with his fabulous Beach BBQ as well. It is a day your family will never forget!!!....Goody

PS...Blue Hole is,I believe, a good 2 hour boat ride from AC. Friends of ours went diving there with a daughter who only snorkeled and they said it was rough and her daughter tired from the snorkeling. And on the way badk it took an extra hour the water was that rough!!! Capt. Bicho will take you to some great snorkeling sites such as Mexico Rocks, Tres Cocos, Hol Chan, and Shark Ray Alley.
