I originally booked my upcoming stay at POFQ through Disney. I booked my fastpasses all at the 60 day window. But now I am seeing a deal on Cheaptickets that gets me the same stay for more than $300 less. If I book that, cancel my other reservation, and assign my new reservation to my MDX account, will I lose my fastpasses? I could wait until the 30-day window is open for my entire stay to cancel if that makes a difference.
