Run Plus Fun is a great place for kids 6 and under. We've attended at least a half dozen birthday parties since it opened.
It's nice to have a place like this so close to home. It certainly is a refreshing change from the Bouncy parties. There's plenty of equipment to play on, there's a section for babies and toddlers, and an area with a couch where parents can sit, relax and talk or use the internet. Compared to a similar place in another part of town Run Plus Fun is small, especially the parents lounge area.
There are a couple of party rooms, clean and big enough for a decent sized party of kids to sit down. Downsides - you are responsible for bringing in and serving your own food. I always like to have the options of full service with party helpers to serve guests. Also, something about it seems a little rushed. I guess its a business and they have other parties booked, but they really seem to be moving things along as quickly as possible while firmly asking the guests to leave.
I haven't been to this place during the open play times but I can definitely see us doing this sometime soon to allow the kids to play while escaping the brutal Vegas heat. Let me say though, that one of the reasons that I haven't visited during the open play times is due to the fact that the hours are pretty much geared toward stay at home moms, there aren't really any evening play times.
