We've been having mini- (Minnie?!) celebration dinners along the way since we planned our Nov trip early this year. We've celebrated the day we selected our accomodations (5 br/5bath) house in Windsor Hills, got our Disney passes, and other milestones on a very long countdown, such as dropping from 3 digits to 2.
We've had a castle cake, Mickey cake, Mickey waffles, and anything else we can think of to give the occasion a Disney touch. Our version of a Mickey cake was inspired by a picture of cupcakes, as was just about the easiest thing to do... we used a chocolate frosting background and with a plain icing tip (a plastic bag with a hole cut would even work!) squeezed three dots of white icing, in the proper configuration, but not quite touching. Flattened with a wet fingertip, they are very effective Mickey designs, randonly over the cake. I do have pictures but don't see any option to attach one.
You can download Park music, DSIL did this ... very cool, and make a dvd with all kinds of wonderful pictures to play in the backgorund. Don't forget to order the free vacation planning video. We watch ours regularly!
