Hi Melissa,
Welcome to the Moms Panel! The first Walt Disney World vacation is pretty amazing, and I have a few suggestions on how to make it extra special for your little princess!
First of all, yes for a child of this age I think it is very reasonable to plan two days to tackle the Magic Kingdom. This makes your schedule a little more flexible, and you will be able to comfortably fit in all of the parades and fireworks, character greetings as well as the extensive list of attractions.
If you are looking for something extra special during your visit to the Magic Kingdom, you could make your daughter an appointment at the
Bibbidi Bobbidi Boutique. She will be transformed by Fairy Godmothers in-Training into a beautiful princess. Advanced reservations are highly recommended and you can make them by calling 407-939-7895.
While you are at the Magic Kingdom, be sure to pick up the Times Guide and schedule a time for you to see the
Dream-Along with Mickey performance at the Castle Forecourt Stage. This is a great way to get to see a lot of the Disney Princesses and other characters in one location during this fun musical celebration.
Another special treat would be to have your daughter surprised with a treat from the Disney Princesses, you could have
"A Royal Welcome" delivered to your resort. The pricing is a bit steep for me, so I tend to hide my own goodies that I've purchased at home within my luggage, it's a lot less expensive, but will have the same effect!
There are so many options, so little space to write...I hope this was helpful!
