Hi Adriana!
Thank you for bringing your question to the Disney Parks Moms Panel!
I can't think of a more magical place for such a magical celebration!
I have seen some really sweet gender reveals take place at
Walt Disney World Resort. I'm not sure what your plan is, but your best bet is to talk to a Cast Member upon arrival to see what they can do (if anything) to help. Please know that there are no set experiences or guarantees, and characters likely will not be available to partake in your reveal. If you really want to have a character interaction for this, you might consider waiting in line to meet the character of your choice and then doing your reveal with them when it's your turn. You can find a list of
character experiences here on the Walt Disney World website. Again, it's always worth speaking with a Cast Member to see if any "magic" can happen that day, but please know that what they can do is limited.
I hope this helps! Congratulations on your growing family and I wish you a healthy and happy pregnancy.
