Hey there, Wendy. Thanks for stopping by the Disney Parks Moms Panel with your question.
Disney's Port Orleans Resort - Riverside is such a fun place to stay. You are going to have a great time. The rapid refill mugs are able to be filled at the
Riverside Mill Food Court which is open from about 6:30 a.m. to midnight daily. You'll only be able to fill up your mug during those hours. However,
extra, Extra Magic Hours is a totally new thing that
Walt Disney World is trying later this year. I checked the calendar at your resort to see if the hours for the Riverside Mill Food Court would be opening up earlier than normal but no changes have been made to the schedule yet. Because it is so new, I'd keep an eye on the
Disney Parks Blog for more information regarding the extra, Extra Magic Hours. If nothing changes in the opening time of the food court, you can always bring up your concerns to the Cast Member helping you when you check-in at the the resort. They might have a great solution for you.
This was a great question Wendy and even though I don't have the exact answer at this time, hopefully we will have more information soon. If you have any other questions, please feel free to come back and ask.
