Hi Denise,
I am so happy that we've able to help you plan your trip because it will be here before you know it! Sounds like you're planning an awesome birthday for your daughters!
The
Celebrate a Dream Come True Parade route begins OR ends in Frontierland near Splash Mountain & travels towards Liberty Square. It turns right at The Hall of Presidents. When it reaches the hub in front of Cinderella Castle it goes to the left side of the hub. From there it heads down Main Street taking another left so that it goes around Town Square, past Tony's Town Square Restaraunt, the Main Street Railroad Station & ends near the Harmony Barbershop.
You can confirm with a Cast Member on Main Street or at Guest Relations from which location it will begin on the afternoon of your visit. In case you forget, the route will be marked on the Guide Map. It is typically held at 3 p.m. but be sure to confirm that on the
Times Guide you pick up when you enter the Magic Kingdom.
If your lunch ends near parade time, you can walk out of Crystal Palace and head over to Main Street. You could also try in the hub in front of Cinderella Castle. If the crowds are packed in by the time your lunch is over, you could head straight out and take the little walk way towards Liberty Square and catch it just before Cinderella Castle.
Wishing your daughters many magial birthday memories :-)
