Hi there, Matthew!
In order to take advantage of the Florida rates that Walt Disney World Parks and Resorts often offers to residents (and how lucky we are!), you will definitely need to provide proof of residency.
You can find a list of acceptable forms of Florida identification
on the Web site.
Looks like your wife can take care of her pass purchase with her current photo identification and one of the bills you share jointly:
"The persons who will use the Florida Resident adult tickets must be present at the time of ticket pick up. If you do not have [a Florida driver's license, State-issued ID, or Florida military ID], then for each adult ticket purchased you must provide one of the following dated within the last two months and evidencing a Florida residential address together with a corresponding picture ID (passport, driver's license, state identification card):
Monthly mortgage statement
Florida vehicle registration or title
Homeowner's insurance policy or bill
Automobile insurance policy or bill
Utility bill
Mail from a financial institution, including checking, savings, or investment account statement
Mail from a Federal, State, County or City government agency."
Have a wonderful time in the World!
See you later, celebrator,
