I have to say I really like this place. I have now gone three times and each time the place is very clean and the staff is friendly. On the times they had extra staff you will see the them engaging with the children and starting games with them. There is plenty of seating for parents to sit and chat while the kids play. At the little kiosk with food they have free coffee for the parents.
A comment states that this place is only good for 3+ I do not believe that. My children are 7, 4 and 2 and all love it. My friend has a 1 year old and both him and my 2 year old are able to climb and play in even the bigger kid area just fine. It did take me or my older kids to show them at first to understand. After that they were physically able to get around without getting stuck anywhere. Smaller kids are allowed in the bigger area unless it gets busy and they will separate the kids for safety. If you are worried about your little one getting hurt when its busy there is a little room you can get to from the front that has a bunch of soft toys and things to climb on. They have little trains that children move by a hand bike which is pretty cute. My kids love that they have bounce balls that they can run around with. The front has a first-aid kit if you so happen to need it. Sometimes they give out helium balloons to the children.
All and all this place is a great way to escape the Vegas weather and really fun for the kids. Only reason I didn't give it five stars is because for someone with multiple kids it can get expensive if you don't want to sign up for the monthly pass. Some might feel $10 is too much but it really is worth the price.
