Can't help you on pictures, but I can offer some descriptions of the Poly's and GF's clubs.
DD stayed at Neverland for a couple hours in December. I would guess the size at close to 2,000 square ft of space. There are sections for different activities (an arcade room, a craft area, toy/play area, and a big "theatre" where they have movies running. Neverland would be great for an active child that likes to do lots of different things. I'm not sure what the child limit is - probably at least 20, if not 30. There was one CM at the desk and 2 or 3 others working the club with the kids.
We also checked out GF's Mouseketeer Club, right next to Gasparilla Grill. MC is a lot different from TNC. MC is one room (maybe 500 sq. ft.), with a large table in the middle for crafts. One wall is lined with computers, game systems. They also run a movie. I think the child limit is 12 at GF, with one CM attending (when we were there). Active children would be boxed in here. But for a kid that wants to play on the computer, play Playstation, etc for a couple hours - this would be fine.
