I've been to Paradise and it is just one beach club after another....so technically you can have the cab driver drop you off in that area and then go to whichever club you want to. You'll need to order drinks/lunch in order to use the chairs/umbrellas. It was okay.
If you are into snorkeling, you might want to see if Dzul Ha is still open...it is a rocky beach, not a sandy beach, and there is great snorkeling there. A cab took us there and when we were ready to leave the bar tender guy called a cab and one came and picked us back up. It was only the 4 of us all day there. Sweet!!
It has been 5 years since we've been though, so I don't know how it is now, maybe not there after Wilma and Charlie went through?
Happy Cruising!
