Will I lose my Fastpass if I change resort dates?

[jaygatsby]

I'm staying at on site for a week but I might have to shorten my trip and come two days later. If I wait and change this after I book my fastpasses for the week will I lose all my fastpasses? Or will I just lose the fastpasses from the days I cancelled?

How soon is your trip? From what a CM at WDW told me, if it's within 30 days, everything stays. If more than 30 days, you may be in trouble.

If you change your dates before you book your fastpasses, it will affect when that 60 day window opens up. I'd make the FP+ selections first, then change your trip dates if you end up needing to do so. Keep in mind that if you change an existing reservation (if it's a package) after the 45 day window and the changed reservation is cheaper than the original cost, Disney will charge a fee. I had to do that once and Disney charged me $50 bucks. Should have taken it out of the hide of the jerk who dumped my daughter 30 days before our trip....
