Us too! Loved the chairs in the pool.
Just to add the cab ride was $15.00 each way (for a party of 4). And a word of warning, when we got off the ship we were approached by people trying to sell us their tours. One asked where we were headed and once we told him he came back with "its 45 minutes away, its very crowded, the cost is $30.00 per person to get in..." all this crazy stuff. I was totally second guessing myself and my research at this point and was ready to get back on the ship.

As it turned out when we got to the bottom where the cabs are the sign right there said $15.00 for the cabs to Paradise Beach. We timed the ride back and that was 17 minutes. It was not the least bit crowded but did start to pick up a little around 2:00 PM. And as Greatfalls noted it was in fact $2.00 per person, $12.00 to use the slides. They do expect you to spend $10.00 per person on food/drink, which was no problem.
For us who didn't want to stay drinking all day and didn't want to snorkel and do all the extra stuff, this was probably the least expensive way to do a beach day. The all inclusive stuff wasn't for us.
