Cayman or Puerto Rico?
 

We are traveling with 2 teenagers this summer and trying to decide between PR & Grand Cayman. I've been to PR and think it overs some variety in activities - rain forest, Old SJ, forts, etc. but don't know about the snorkeling. We really like to snorkel. Cayman has the beach, stingrays & turtles...but what else to fill the week? I've been on a couple of websites but am still undecided. We will be staying on Marriott properties.
Thanks! Mobyfar

The turtle farm is a great source of entertainment. So are the submarines and the sailboat cruises.

I think you would be fine in Cayman. Above post is correct the submarines are excellent! If you love snorkeling there is great snorkeling on GC. There is also a busy downtown to tour, the turtles, Hell, and I belive there are some historic sites to tour as well. The beach alone is enough to get me there.

Don't forget about the Botanical Gardens in Grand Cayman, I think you would all enjoy them.

Thanks-it was the botanical gardens I was thinking about!
