My expectations of this place weren't high after hearing about other experiences, BUT I actually had a pretty great time!
I feel like if you're going to go here, pay the extra $20 to enjoy the pool - and go early. My friends and I came here 30 minutes after they opened, and had a good hour or two to enjoy the pool almost to ourselves. The mojitos and piƱa coladas were pretty good, as well! Sadly we still didn't get one of the few chairs by the pool.
My biggest complaint: it seems messed up to only offer shade/seats to those willing to pay thousands of dollars for a cabana. Sadly, the day ended with some minor heat stroke.
