We stayed at the Poly two years ago and LOVED it for small kids (ours were 2, 4 & 6 at the time). It was especially nice with our toddler because we could just wheel the stroller right onto the monorail without taking him out of it. (The buses were a lot more stressful, not only because of the longer waits, but because DS 2 was unused to riding in any vehicle unstrapped, and kept crying to get off my lap and run around.) We could easily catch the resort loop to the MK from the Great Ceremonial House or the Epcot monorail from the TTC, both in walking distance from our longhouse. There's also the ferry from the TTC or the boat launch direct from the resort if you want to change things up. The fireworks were visible from the resort if the kids were too tired to stay for Wishes; the volcano pool and beach were great for the older kids when the younger one was napping; Captain Cook's has decent counter service if your kids, like ours, get antsy at too many sit-down meals. We're going back next year, and I'm on the fence about going Poly again or trying the Wilderness Lodge, since the kids are a bit older, For young ones, though, I'd say Poly, hands down.
