That is correct, just grab a taxi to PB. Agree on the price before you get in the vehicle and be sure to have lots of small bills so you can make exact change. It is possible that the driver won't be able to change a $20, so that would end up being your fare.
If you check out their website
http://www.paradise-beach-cozumel.net/ it has alot of info... It was by far the nicest day we spent.
There is no fee for beach entry, but there is a fee if you want to use the water toys - trampoline, iceberg, etc. You can also rent snorkel gear, though the snorkeling is not great there.
Food is great - the nachos were outstanding. I can personally recommend the marguerita's, I tried several to make sure they were good.
We used a Visa card to pay, so I know they take that. Our total bill, which included 3 Margueritas, 4 Coronas, buffalo wings and loaded nachos was about $40 US.
Have fun, and make sure you say to PB Tom for me! He and his staff do a great job there, I'm sure you'll have a great day.
