Hey there, Susan. Thanks for stopping by the Disney Parks Moms Panel with your question. I see that your trip is next month, you've got to be getting so excited!
The information that you've read is correct. Busses do start running from the
Walt Disney World Resort Hotels to the
Walt Disney World Theme Parks about 45 minutes prior to opening. Even if you are on the first bus, I just don't think that will give you enough time to travel between
Disney's Port Orleans Resort - Riverside to
Epcot. What I do suggest is using
Disney's Minnie Van Service instead. You can request a Minnie Van using the Lyft mobile app, so be sure to have that downloaded on your phone before your trip. Minnie Vans start running at 6:30 a.m. daily. When you are ready for a ride, simply open the Lyft app. If the Minnie Van isn't the default vehicle displayed, just swipe through the options until you see it. You'll then enter your destination, see travel times and pay all conveniently through the app. It's really fun to take a Minnie Van. I enjoy chatting with the Cast Members driving and who wouldn't want to ride in a polka-dotted vehicle? If this isn't something you'd be interested in, you might want to call and push back your breakfast reservation a little bit so you don't miss it.
I hope this helps! If you have any other questions, please feel free to come back and ask. Enjoy your trip.
