I could be wrong, but it looks like THIS IS IT!
Given that the link still goes to an active page and it's clearly a fall offer, I think this is for real. The fact that it went up prematurely on the Special Offers page was clearly an IT mistake. I am able to click through it to reservations but no discounts are showing up for any resort; it's all rack rate. That could be an availability issue but I suspect the code just isn't working yet.
So -- what does this mean? That $63 is the same price they quoted for the last Room-Only discount (40/30/25) advertisement. The only difference here is that it's not "room-only" in that they have it set as a package with the tickets. Not a big deal for those of us looking to book our whole trip; but this will affect anyone trying to book one day before FD.
Half an hour ago I would have said tomorrow wasn't likely -- in our review of historical discounts on MouseSavers, the only day that never showed up was Friday. But now I know
i'll be up bright and early tomorrow morning. And every morning after that until this goes live.
