Hi there, Amy!
One More Disney Day is an absolutely incredible promotion that involves an equally incredible amount of planning. Disney is presently in the final stages of working through the logistics of this celebration, and will be releasing details soon.
Disney has a huge online community of fans, and there's loads of places for enthusiastic speculation. Right now, your best sources for news and "rules" of the promotion are best found on official Disney sources, including the
One More Disney Day site and the
Disney Parks Blog. The blog, in fact, is updated multiple times per day, and is often is first with the most current information.
Keep your eyes on those two sources as the time draws closer, and I'm confident that if your question isn't directly addressed in a FAQ from Disney, you'll be provided with a contact telephone number for further information.
Please bear in mind that there is a special offer happening in conjunction with the promotion: Guests get one more day and night free when they buy a 3-night/3-day non-discounted Walt Disney Travel Co. room and ticket package at select Walt Disney World or Disneyland Resort hotels. The package offer is good for arrivals most nights Feb. 26 – March 10, 2012 and must be booked by Jan. 31, 2012 .
Thanks for your patience!
See you later, celebrator,
