Hi Melissa,
How exciting it must have been to see your daughter's face projected on Cinderella Castle in the middle of the Magic Kingdom! I've seen the show a few times and I think it is simply enchanting.
You should check the Times Guide as you enter the Magic Kingdom to confirm the performance schedule for
The Magic, The Memories, and You on the day of your visit. I have noticed during recent trips that they typically start The Magic, The Memories, and You fifteen minutes before the scheduled start time for the Wishes nighttime spectacular fireworks. On some nights, however, they also run The Magic, The Memories, and You after Wishes so be sure to double-check the Times Guide.
Plan to arrive 20-30 minutes before the show to grab an unobstructed viewing spot. I like to find a location near the Partners statue in front of Cinderella Castle.
Although the photos displayed on the castle change daily, I'll keep my fingers crossed that you will get to see your daughter's picture again during your next visit.
Have fun!
Jill
