I love this one cause not only do I remember it from when I was a kid but also now that I have my own kids they love it as well..
My friend has this for his little girl! They had it out and the littles was playing in it last weekend at a BBQ. It looks like sooo much fun! All the kiddos was entertained and running around for awhile! All kids were under 4, I don't know if that helps or not... https://www.shopswell.com/products/intex-rainbow-ring-inflatable-play-center-117-x-76-x-53-for-ages-2
I want a kiddie pool also soooo bad with like neat things on them! I've seen a couple at Walmart but I haven't decided what one I want. Definitely following your post.
I like this one because it keeps the kiddos shaded some.
