Uwanja camp AKL height limit?

[Wendysofftoneverland]

My kids love the kids' water playgrounds, like at SSR, but my oldest is 3 inches away from reaching the 48 inch height limit. I noticed the AKL Uwanja Camp is described by ages. Is there a height limit? Can a 4 year old and 6 year old play in the same section? The website describes the areas as 4 and under, 5 to 7, and 8 and up. Also, can both Kidani and Jambo use it? Thanks!
