Took our grand daughter here on an August Sunday afternoon. It doesn't open 'til 1:00 pm. Bear in mind that sheltered tables can be reserved, and shade is at a premium. And while the artificial surface covers everything, it can get pretty hot. Plan on water socks or flip-flops between the features.
This is a park for families with younger children. Teens might be a little bored, although the water slide tubes are exciting (if you're over 48" tall -- they DO measure). You CAN bring in an ice chest, which will be checked to ensure there's no alcohol or glass. A small amount of food is sold inside the Center. Arriving early, gave us a chance to "claim" a couple of lounges and move them against the wood fence for a modicum of shade, later in the day.
The lifeguards did a good job of watching for unsafe acts (mostly running), and to keep kids away from the discharge ends of water slides.
Congratulations to the city of Round Rock for creating an affordable and safe water park.
