Buy at the price that makes sense for your situation. Trying to time the bottom is a waste of time.
This is it right here is said perfectly...the bottom may have already happened, prices and sales are higher than a few weeks ago already and less inventory is driving them up. Also, a lot of dates at Disney are fully booked through the end of the year so I think the people that were feeling the crunch have already listed and/or sold.
But bottom line is, for example on 100 point contract, if you buy at $135 or $125...your looking at a $1,000 difference. On a $15,000 contact that really isn't that much of a difference. Plus other factors...stripped or loaded. Right now that discount is coming on stripped contracts but thats one less vacation on the 100 point contact so that $1,000 dollars at the minimum is more of a wash. In my opinion buy what you want if you can afford it (without a loan, I'm assuming the rates are high like the direct rates).
