Here's the deal, I am planning a vacation to WDW in May. I got the FD pin plus we're due for a vacation. Only problem is that my Mom is scheduled to have surgery some time in May. She will know more the beginning of April. And while the surgery isn't life threatening there are some risks associated with it. If they schedule her for surgery while we are supposed to be in FL, I would rather re-schedule my vacation until later. My final payment for my WDW portion is due April 2nd. And like I said, my Mom's surgery isn't scheduled until the beginning of April. If I re-schedule my WDW dates after April 2nd do I get a penalty? What if we decide to make our WDW stay shorter and thus reducing out package price? Is there a penalty then? (if we do this after April 2nd) What about if I scheduled our stay at WDW for fewer days and then added additional days later?
