Hey there Joshua! Thanks for stopping by planDisney with your question. I speak for all of us non-Floridians when I say we are jealous that you can still buy
Walt Disney World Annual Passes! Meanwhile, Walt Disney World put the Frozone freeze on the rest of us!
I chatted with a Cast Member from Guest Services and verified that Theme Park tickets can be
upgraded to Annual Passes, as long as there is one valid day remaining on them. However, four-day tickets are the maximum number of Florida resident tickets that can be purchased, so you would not be able to add a fifth day to your ticket during your visit.
However, after upgrading your tickets to Annual Passes, you would be able to add another day to your trip by simply making a
Disney Park Pass reservation. It's not a guarantee that your desired park will have availability, but it's worth a shot! If you would still like to upgrade your four-day ticket to an annual pass, make sure to speak with a Cast Member at a theme park ticketing window and do so before you use your final park day.
I hope this helps, Joshua! If you have any more questions, drop back by and
ask me!
Until next time,
PG
