This year does seem to have atypical booking availability from previous years - i.e. Boardwalk is still available for Food and Wine for some nights. Whether this is because people are booking BLT and VAKL (which has lots of rooms) or because the economy is making people postpone their trip or take one less - who knows.
My money is on the people who take an extra short trip for F&W not doing it this year, its a pretty common thing for
DVC members to squeeze in a short F&W trip - they'll use those points to extend their "more normal" vacation so they only have to pay for travel costs once.
