The water options/slides are fantastic! My two kids (8 & 9 yrs old), husband and I loved them.
They need to make it more clear that children get measured in a certain spot to get a colored wrist band that coordinates with their height for certain slides.
It's not cool that the arcade's prices go up at 7pm every night, so you need more points/tokens for each game then.
The A/C in our unit was super loud with an extra sound, which kept my 8 year old awake.
The gluten free pizza in the restaurant right next to the arcade was pretty good. (My husband said it was better than the regular pizza.)
FYI, you cannot check in at a kiosk if you book through a third party (like Expedia). You have to wait in line for a front desk agent, though the line moved quickly.
Be sure to pay for parking upon check-in. If you try to do it outside at the kiosk when you're leaving, it will say you owe more than you do, per hourly, instead of the overnight guest rate. (The kiosk said we owed $52, whereas when I went inside and asked a rep for help, we actually owed $30.50, including tax, for the night.)
Overall, had a great time.
