Hi Marianne!
Hooray to you both for having a whole year of Walt Disney World fun ahead of you! I have good news to share. It's super easy to upgrade your Florida Resident Annual Pass from the Disney Weekday Select Pass to one of the other options (you can read all about those
here). To do that, just stop by any Guest Relations locations at Magic Kingdom, Epcot, Disney's Hollywood Studios, Disney's Animal Kingdom Theme Park or Disney Springs and a Cast Member will help you with that.
If you're taking advantage of the monthly payment program and want to roll the additional costs into those payments, you must complete the upgrade within 14 days of your original purchase. Otherwise, you'll just need to pay the difference out-of-pocket at the time you make the upgrade.
I hope that helps, Marianne, and wishing you a most magical year!
Beth
