Hi, Kari!
Welcome to the Disney Parks Moms Panel!
Forms of payment accepted at Walt Disney World include Visa, MasterCard, American Express, Discover Card, Diners Club Charge Card, Japan Credit Bureau,
Disney Gift Cards,
Disney Dream Reward Dollars, and
Disney Visa Instant Credit. All of these are accepted throughout the theme parks, water parks, Disney Springs, and the Walt Disney World Resort hotels.
There are a few outside and stand alone vendors that only accept cash. These outside vendors typically are supplying items such as souvenirs, snacks, and beverages for convenience. All of these same items can usually be found inside a store or shop that accept credits cards.
Kari, I am sure that while you are visiting Disney you will have no problems finding what you are in need at the locations that accept credit cards.
Enjoy your upcoming Disney vacation!
Happy planning!
Korliss
