Entertainment Rehearsals Taking Place Overnight (MK)

If you will be staying at one of the Disney Resorts around the Seven Seas Lagoon in the next few days, note this:

Please, note that entertainment Cast Members will be conducting overnight rehearsals at the Magic Kingdom Park. Guests staying at one of the Resorts located around the Sevens Seas Lagoon (Grand Floridian Resort & Spa, Polynesian Village, Contemporary Resort, Bay Lake Tower) and Bay Lake (Wilderness Lodge, Fort Wilderness Resort & Campground) can anticipate noise impacts with some pyrotechnics on November 3-6, 2013 from park clear (usually two to three hours after the park closes) until 7 a.m. 

So, why are these rehearsals taking place? Is a new show going to (finally!) replace "Dream Along with Mickey"? We personally think that these entertainment Cast Members may actually just be rehearsing for the usual seasonal show coming soon to the Magic Kingdom Park (for the after-hour parties). That said, you never know...
