I took my 4 1/2 year old grandson to this facility while visiting DC. To charge $10 for a child to play ONE HOUR with a bunch of balls, climb up ladders, slide down tubes, and play with other kids (Oh! sounds like a park playground, right?) is daylight robbery, so I decided to pay $15 for the entire day, because my son told me that my grandson would enjoy it. When my grandson decided he wanted his milk and I tried to go to the vehicle, I was advised we could not regain admission, so we remained, and bought a drink from their in-house cafeteria! We all know that young children's attention span is very short, so how long would they be satisfied with the above (repetitive) activities? We left after about 2 hours, and he didn't even object to leaving. Like me, I guess he'd had enough! In fact, he spent the last 30 minutes or so, playing the video games. Next time, we'll just go to the park and take a tablet!
