A number of years ago we were at a private corporate party and it was a blast. They brought everyone in on buses through the Streets of America. There they had set up a red carpet complete with "fans" and "paparazzi" lining the area where we exited the buses. They were asking for our autographs as if we were all famous.
Then we were taken into the Indiana Jones theater where we could grab whatever snacks we wanted on the way in and then that show was performed special for our group. This was while the park was in the process of closing.
After the show, we were taken to Sunset Blvd. where there were tables with food set up and a band playing. TOT was open all evening (this was pre-Rock 'n Roller coaster days) as was the Great Movie Ride. At the end of the evening, they handed out beverages and ice cream bars to the group before they did the Fantasy in the Sky fireworks. I'm sure the DIS doesn't have anything quite this elaborate in mind, but thought you'd all enjoy hearing the experience we had.
The next time we went on a corporate trip with this same group, they had their special party at Universal Studios. It was a 0 by comparison to the party at Disney.
