I just got off the phone with Disney and spoke with Guest Communications. She was of no real help because she couldn't confirm or deny what Disney has planned to do in reference to closing at 6:00 or 7:00 and clearing guest without wristbands. I did however get the following addresses from her. She said they would be able to clarify this for me.
www.guest.communications@disneyworld.com
or
Walt Disney World Guest Communications
P.O. Box 10040
Lake Buena Vista, FL 32830-0040
I'm planning on inquiring about this rumor further.
