So, I don't want to be "Negative Nancy," but I stayed once and we haven't returned. Let me give you my frank opinion.
On the plus side, the theming is very kid-friendly, particularly if kids are under 10 or so. If your kids are into any of the movies highlighted there, that's great. The pool area is great and also kid-friendly. We stayed at the Lion King suite (the one with the Murphy bed) and it was spacious and nice. The kitchenette was a major plus.
On the down side, there is a lot of walking as mentioned. But what kind of bugged me the most was just how jam-packed the resort constantly was, no matter what time of day. For me personally, I want some respite from the crowds at the parks and felt that I never got away from the commotion. I'm willing to pay more just to feel like I'm actually on vacation for a few hours back at the hotel!
Regardless, you and your family will enjoy it.
