And also from Mouse Planet:
As of October 5, the
Garden Grill opens only for dinner, and will no longer be open for lunch.
As of January 5, 2009, the
Liberty Tree Tavern is no longer offering character dining. Dinner will continue to be serverd without the characters.
The big change appears to foreshadow a major policy change. As of July 16, you will not be able to make any Advance Dining Reservations (ADRs) for any dates past January 15, 2009. ADRs needed for January 16, 2009 or later will not be able to be booked until October 15, with the following three exceptions: Chef Mickey's, Cinderella's Royal Table, and Victoria and Albert's.
It looks like Disney is preparing to move the reservations window from 180 days back to 90 days, with the exception of the three most-in-demand dining locations. While the days of walk-up, same-day reservations everywhere are probably gone forever, it'll be nice not to have to worry about what you want to eat half a year in advance.
