I love the GC. It is close to the DL entrance, the heart of DTD, and has it's own entrance to DCA. Prices can be high, but I have often gotten much better rates on cheaptickets or expedia.
DLH is my second choice. Love the theming in the rooms. The armoire has a map of DL on it, the wall border is tinkerbell and pixie dust - which glows in the dark, and the lights above the sink are held by big mickey hands! It is a bit of a walk to the DCA entrance, but you can take the monorail into DL. It sits at the very end of DTD.
I have not stayed at PP, but have noticed that it is quite a walk to the park entrances (it used to have it's own entry into DCA but it has been closed off).
