DCA Open Early to Grand Californian Guests?

[MegarooFifi]

I've heard that the Grand Californian guests are able to go into DCA (No attractions are open or anything) early so you can walk around (say if you are a runner or walker or so forth...). However, on our last trip, we never got up early enough to go into DCA when it wasn't open, so I'm not sure. Does anyone have experiences with this?
