Jungle Rapids has plenty of options for entertaining children, especially kids ranging from 7-12. The arcade is plentiful (requiring tokens aplenty, but you do get tickets that can be redeemed for small, inexpensive prizes). There is laser tag, go-carts, a small water park, small rock wall, a small food court, etc. The place is tired and a bit run down. The women's bathroom wasn't exactly "fresh" by closing time (when I needed to use it). The young lady behind the prize counter wasn't rude but she certainly wasn't cheerful either.
My kids thought it was great but they also think Chuck E Cheese is great, whereas I do not. So I think Jungle Rapids is a fine way to pass an afternoon, but it's not my favorite way to do it and I don't highly recommend this. Compared to the other local attractions in Wilmington (Battleship, Serpentarium, etc), I would just as soon skip it. For water fun, there's the beach!
