As Disney begins to relax their COVID-19 safety procedures, guests are now allowed to use self-service stations to fill their refillable mugs again.
Disney changed their website to reflect the new protocol as you can see below:
“Some self-serve beverage stations—which allow for Guests to fill and refill their own beverages—are available at select quick-service restaurants located in Walt Disney World theme parks and Disney Resort hotels,” Disney added to their website.
Blizzard Beach has been allowing guests to refill their own beverages since it reopened in March, however, since Disney World reopened last summer guests at other Disney World locations had to be served by Cast Members.
