Depending in when you're going and the time you arrive to the water park, there may not be too many places left to "chill". We had waterparks included as part of our tickets last year. We got to TL at about 10:30am on a weekday during September (it opened at 10am). The only places left to sit were on those tiny small chairs that are packed next to each other, no room in between you and the person next to you. And off to the side of the wave pool. It was not a place to chill. It was more like people soup. We did a few laps on the lazy river and left. I won't go this year, even for free. If I'm going to "chill" it's going to be at my resort quiet pool. So when my room is ready, I am right there.
