Hello, Jaynee!
While it is true that all Value Resorts will be receiving mini-refrigerators some time this year, a specific schedule for each resort has not yet been released.
However, if you want to try to have a mini-fridge in your room, you can always request to have one in your room for an additional $10 per night, plus tax, based on availability. See
Disney's Pop Century Resort webpage, under "Amenities & Services" for more information. Check back on this webpage often, too, or call Walt Disney World Reservations at (407) W Disney [(407) 934-7639] from time to time to check on the installation of these mini-refrigerators at your resort.
Please be sure to send any additional questions you may have as you plan your upcoming trip to Walt Disney World! I'd love to help!
