I thought it was pretty cool for little kids. I wasn't sure what to expect as I had read other reviews about other indoor play areas. I didn't see anyone clean anything once during the 2 hours I was there so hopefully they Clorox wipe everything after everyone leaves? They do provide Clorox wipes for you though, but when there is that many toys it's hard to keep up with wiping everything down especially things like the ball pit.
My daughter had a fun time as we had met up one of my friends here. One of the issues that I have is that there were kids that were throwing things and their parents didn't notice or supervise. When a kid is throwing books and trucks into the ball pit when there's other kids in it with no repercussions...that's not cool. We ended up having a kid follow us around which was ok but he kept interrupting us when we were trying to play.
Toy selection is pretty varied. I do like that it does provide toys from when they are babies to an older age. There's free wifi and couches to sit on. I couldn't sit with my 1.5 year old constantly needing supervision but I can see how it can be relaxing for parents with older kids. They sell snacks there too. Make sure you go when they open because even though I went at 4 and they closed at 6 I did have to pay the full $12 dollars which is the cost for one day with in and out privileges. It is definitely worth it if you do it that way. Overall it was a positive experience and I would go back.
