That pink castle has to be one of the most controversial creative decisions in WDW history.
During the year that they had the cake castle, they did something a little different at the Disney Wedding Pavilion (over by the GF).
The chapel is set up so that the altar is beautifully framed by a window with Cinderella's castle, off in the distance, smack in the middle of the window.
Evidently, there were complaints about That Thing in the Magic Kingdom ruining the wedding pictures.
So the pavilion began providing a stained glass window of the original castle that could be inserted, in case you wanted THAT instead.
Personally, the pink castle didn't bother me, and my wife thought it was fun. But the thing had a hard time staying inflated, and I remember during our stay there were constantly cranes working on it, or parts that needed repair.
