Have a tight time scenario coming up. I have 5 day park hoppers I purchased online from UTC for our upcoming Dec 3-7 trip . Plan to upgrade to DVC annual passes after entering and exiting a park, probably on Dec 4th. Here is the issue- we are also planning a trip Feb 3-7 and our Fastpass window is on December 5th. Will my upgraded passes show up in the My Disney Experience App when I try to book fast passes on the 5th? Anyone have any experience with this??
