Hello, Heather! You came to the right place: we're all about doing it right (not so much into doing it once, I'm afraid)!
Since your trip is more than a year away, I'm going to share advice about activities and locations that are not currently being offered due to health and safety precautions. I suggest that you check these offers to adjust your plans accordingly as we get closer to October 2021.
I'd suggest five Theme Park days in total, beginning at
Disney's Animal Kingdom Theme Park. I think that the kids will love the Wilderness Explorers trail of self-guided activities, Pandora – The World of Avatar, the Kilimanjaro Safaris and a lunch at Tusker House. This meal will allow you to sit indoors and meet Donald Duck, Daisy Duck, Goofy, and Mickey, so that's a major time-saver!
Then I suggest
EPCOT, where you'll find many tasty adventures and multi-cultural stimuli. You'll likely visit during the Epcot International Food & Wine Festival, so you'll take your children on a tasty stroll around the world!
I suggest that you take the third day off to enjoy your
Disney Resort hotel and relax by the pool. The perfect breakfast for this day is at
Topolino's Terrace – Flavors of the Riviera, where Mickey, Minnie, Daisy, and Donald will welcome you for a fantastic, leisurely morning.
Then, on the fourth day, it's time for my favorite place:
Magic Kingdom Park! I suggest making a lunch reservation at
Cinderella's Royal Table so that you get a break in the middle of the day to meet Cinderella and other princesses
inside Cinderella Castle. This is the ultimate Disney experience!
The next day would be at
Disney's Hollywood Studios, where you'll have a wonderful time both at
Star Wars: Galaxy's Edge and
Toy Story Land. Docking Bay 7 Food and Cargo is the place to have lunch there, and I suggest that you don't skip dessert. After that, I suggest that you repeat the Theme Park that you enjoyed the most so that you can soak all the magic in!
Since you want this trip to be perfect, allow me to suggest my favorite Disney Resort hotels:
Disney's Animal Kingdom Lodge,
Disney's Polynesian Village Resort, and
Disney's Beach Club Resort. They will offer you exceptional amenities, top-notch dining alternatives, unbeatable location and impeccable theming. How do they sound?
We'd love to give you more advice on how to make dining reservations and refine your plans, so don't hesitate to come back to planDisney!
May the magic be with you,
Julie
