We don't use those places, but everyone seems to rave about the one at Poly..."neverland" and, you could catch the monorail from TTC straight to epcot.
If you are staying at AKL, why not just use the one there? Alternatively, what about a service like "Kid's Night Out"? That way if the child is tired they can be in their own room rather than stuck in the kids club until you get back, and you won't feel the need to get back at any given time?
We stayed at AKL once and were in the food court one night, and saw a "grandmotherly like" lady sit down with two kids, some board games and their meals, and I'll tell ya, I was impressed! I got talking to her and learned she worked for Kids Night Out. I used to swear I'd never use a babysitting service until I witnessed her interraction with the kids. It was kind of cute..the kids looked like "Jane and Michael" from Mary Poppins. LOL
Just another option for you...I don't know how much the prices differ.
