This is true. When we were there last week, we stayed one night at the PPH before transferring to the GCH the next day. I stopped by the desk at the GCH the evening we arrived just to see if they could tell me if my room requests had been honored. They told me that "as of now" I had been assigned a particular room with all my requests, but that could always change as guests checked in the next morning and they might need the room I had already been pre-assigned. DH headed over the next AM while we were in the park and checked us in about 9 am, just to be sure. We did get our requests.
