Hi MaryAnne,
Thanks for stopping by the Disney Parks Moms Panel with your question! I'm hoping I haven't missed your trip! One of the latest openings since your last visit is
Princess Fairytale Hall in the Magic Kingdom. You could get some fantastic pictures of your granddaughters with their favorite princesses! There is also an incredible new daytime parade in the Magic Kingdom,
Disney's Festival of Fantasy Parade. From everything I've heard, it is not to be missed. If you aren't traveling until later this spring or early summer, the Seven Dwarfs Mine Train will be opening.
If you're like me, there is never enough time to see everything you would like to in the parks. I try to do something new to me on each vacation. If you haven't tried the Animator's Academy in Disney's Hollywood Studios I highly recommend it. If you haven't seen all of the great shows available, this might be the trip to take those in.
Please let me know if I can answer any other questions for you.
Wishing you and your granddaughters a magical vacation,
Amy H.
