Hi Patricia!
I'm sure you can't wait to see your daughter's face as she soaks in all the amazing experiences that Walt Disney World has to offer. I have a few ideas that come to mind because we took our niece on her first Disney vacation when she was 5. As Peter Pan said, "Here we go..."
Tip #1:
When you make your first trip to the Magic Kingdom, walk ahead of your daughter so you can get a picture of her reaction to seeing Cinderella's Castle for the first time. It'll be an awesome souvenir that you'll cherish forever.
Tip #2:
To carry on the feeling of being a princess, I'm guessing your daughter would absolutely love a visit to the
Bibbidi Bobbidi Boutique for a royal makeover. There are two locations to choose from, one inside Cinderella's Castle in the Magic Kingdom and one in Downtown Disney.
Tip #3:
Great job snagging a reservation at Akershus Royal Banquet Hall. Your daughter will love interacting with the Princesses there. If you want another unique dining experience for her, you may want to consider
My Disney Girl's Perfectly Princess Tea Party at Disney's Grand Floridian Resort & Spa.
Bonus Tip:
Plan for some down time at your resort hotel in the middle of the day. When my niece was that age, giving her some time to play at the pool or even do some of the activities at our hotel was a nice way for her to recharge her batteries.
I hope that helps to point you in the right direction. If this sparks some ideas or other questions, I'd love to hear back from you.
Otherwise, I hope you have an awesome vacation!!
