the meals are actually going to be plated and brought to you, not buffet style. so you wont get the custom eggs and omelets and what not.
heres info from allears:
UPDATE: The Grand Floridian Resort's 1900 Park Fare will close for refurbishment Monday, July 9, 2007, through Monday, October 1, 2007, and is scheduled to reopen October 2, 2007. During this time, the Grand Floridian Cafe will become the site for both the "Supercalifragilistic Breakfast" and "Cinderella's Gala Feast." These will both be character meals, but NOT buffets (as they are at 1900 Park Fare) -- they will be pre-plated character meals.
The a la carte menu usually offered at Grand Floridian Cafe will NOT be available there during this time. Citricos (located on the second floor of the Grand Floridian), however, will expand its hours and menu to include a la carte breakfast, lunch, and dinner seven days a week. If you want to dine at the Grand Floridian Cafe during this time, it can be ONLY for the character breakfast or character dinner -- you will NOT be able to book a reservation otherwise.
In addition, the Wonderland Tea Party will NOT be available during the 1900 Park Fare refurbishment.
