Could this also be the economy in general? This forum isn't going to be a great representation of the general economy; everyone here is hardcore Disney fans and either already had strong incomes (people doing multiple trips a year, annual trips, etc), or cut away everything else so the Disney budget remains.
We've seen loads of news on how people are nervous about the economy and debt loads are higher then they've ever been... maybe just softer general population demand? Or resellers don't think this is the safest bet this year? (Or the funny option, Disney somehow actually did something to block the bots? lolz)
