I'm never sure if you can fully trust Disney's marketing department but my mother received a brochure in the mail this past Saturday that is numbered CST #1022229-50. On the mailing label panel, it says "We're conjuring up Disney fun for this February!" Inside, it says "The February vacation you wished for is starting to materialize!" Also inside, under a paragraph labeled "Have a Ball.", it says "Beware! You may find yourself taking a sneak 'peak' ride on Expedition Everest -- Legend of the Forbidden Mountain..."
All of the text mentioned above is pre-printed text on the brochure, i.e., it is not printed at the last minute by the mailing label printers.
I should also add that we are not DVC members, AP holders, or members of any other special sneak preview "class".
4 weeks from tonight I'll be sleeping at WDW!
