Hello Mindy!
First of all, Happy Birthday to your daughter! She is going to have the BEST day at the most MAGICAL place on Earth!
While Disney World does not give balloons or a card for guests on their birthday, I would highly recommend picking up a Happy Birthday Pin at your resort or at Guest Services in any of the Disney Theme Parks! I promise your daughter will receive so many Happy Birthday wishes!!!
I checked with a Cast Member about the Magical Milestones Tour, and it is no longer available. However, she recommended the three hour tour called
Inspiration Through Walt's Eyes. This tour covers multiple parks, and Disney Theme Park admission is not required. The cost for this tour is $105.44 per person. However, this tour is only availble for those 16 year or older. (I am not sure if you want to experience this tour without your daughter, but I still wanted to give you this information.) If your whole family wanted to experience a special tour, just click
HERE for all the incredible tours available for Disney guests!
I hope this helps you out in your planning. If you have other questions, please let me know.
Have a MAGICAL day, and Happy Birthday!
