Hello Cathryn,
I think you should be nominated for best grandparents of the year for taking your twin grandchildren to Mickey's Very Merry Christmas Party (MVMCP)! If you plan to eat in Magic Kingdom during the Party, I would like to suggest making reservations at
Liberty Tree Tavern. Not only do I enjoy eating at this Restaurant, but timed right, you and your family can have prime parade viewing spots as you step outside after dinner.
Regardless of where they start, parades typically will wind their way through Liberty Square and
Frontierland. Sometimes I see guests line up along Main Street, U.S.A.
for hours prior to the parades, forgetting about other spots along the
route. In Frontierland, my family always benefits with a little more
elbow-room.
MVMCP is such a magical event. I hope you and your family have a fabulous time!
