I stayed there on my last weekend trip to Epcot. It was a very nice hotel for the price. Beds were ultra comfy and we enjoyed that it had a little disney store inside as well. I'd still prefer to stay even in the values over here since the disney transportation to the parks is much better than what they use, but the hilton was even cheaper than the values that weekend so we stayed there. It is right next to downtown disney however so walking over was a breeze.
Overall a very nice hotel. I don't get that disney immersion feel like I do when I stay in a disney resort but still a nice hotel.
Adding my thanks also. My office just booked me into the Hilton for next week w/o my knowing (yes, a Poly MK view would have been better) but at least it looks like I have nothing to worry about.
