Hi Angela,
Thank you so much for visiting the Disney Parks Moms Panel with your question. We on the panel love helping guests to plan magical vacations!
I absolutely love watching Tinker Bell fly from Cinderella Castle at night at
Magic Kingdom. There is something so truly magical about watching her light up the night sky. The first time I visited Walt Disney World as an adult, I was absolutely not expecting to see Tinker Bell flying overhead, and I will never forget my complete astonishment at seeing her glide above me!
I have great news for you. Tinker Bell does still fly during the
Happily Ever After nighttime show! This show features fabulous fireworks and wonderful projections on Cinderella Castle, and plays nearly every night at Magic Kingdom. Do check the schedule on the link I provided for specific times for this show on the dates you plan to visit Walt Disney World. The first time I saw this show, I was not sure if Tinker Bell would fly, so I was thrilled when she did! Tinker Bell does fly closer to the end of this show, so do not worry when you do not see her right at the beginning. Also, there may be some times when Tinker Bell does not fly, which I believe are weather-related.
I hope that these thoughts are helpful for you, Angela. Please do let us know if you have any further questions.
