MousePlanet's David Koenig has some interesting info regarding the future of DCA's Corn Dog Castle:
David Koenig 6/30: Dumbo's Secret Identity
Will DCA Keep Its Castle?
Plans are for the Corn Dog Castle, which closed earlier this month, to return to Disney's California Adventure, just not in its original location. Imagineering hopes to relocate the fast-food stand to Carsland by 2012. Could Souvenirs 66 be close behind?
Obviously, this conflicts with information I previously received, which said that Corn Dog Castle and Souvenir 66 would stay in their current locations, just with new theming, and in the case of Souvenir 66, a new name (Seaside Souvenirs).
We'll see what happens... in the mean time, I've updated the Corn Dog Castle entry with details:
Corn Dog Castle retheming
Details: The quick service dining location was originally said to be undergoing a Victorian-style re-theming in order to match the surrounding area's new theme. A June 30 report from MousePlanet's David Koenig says otherwise, however, indicating the dining location will be moved from its current location and reopen at a new location in Cars Land in 2012.
Project Status: In progress. Construction walls went up June 1, 2009
Open Date: Cast Member publications currently list it as returning June 2011, but that date may be in flux and can change, especially if rumors of a Cars Land relocation are true.
