Hello, Susan,
Without hesitation, I would recommend including Epcot in your plans. In Future World, there are some fantastic attractions like Test Track, Spaceship Earth, The Seas with Nemo & Friends, Turtle Talk with Crush, and my absolute favorite attraction Soarin'. It also has a fantastically unique water play area outside Journey Into Imagination. And if your family likes extreme rides, Mission: SPACE has both intense and mild options. After visiting Future World, the World Showcase is a wonderful celebration of 11 countries where your daughters can visit the
Kidcot Fun Stops for personalized (and free!) souvenirs as well as go on an adventure with Phineas and Ferb at
Agent P's World Showcase Adventure.
So if you visit each park, that is essentially 4 of your 7 days. It is nice to have one day where you can sleep in and enjoy your resort's pool. You can also head to
Downtown Disney for shopping and dining fun. The
Water Parks and
miniature golf are also fun breaks in the week. If your daughters like tea parties, they may find the
Afternoon Tea at the Garden View Tea Room or My Disney Girl’s Perfectly Princess Tea Party a lovely experience. If they are adventurous, they may also enjoy the
Pirate Adventure Cruise.
With your remaining time, it is fun to go back to your favorite attractions and parks!
