Hey there, Hi there, Ho there, Adriana!
Thanks for stopping by the Disney Parks Moms Panel. How wonderful that you will be at the Happiest Place on Earth for Mickey Mouse's 90th Birthday on November 18, 2018! I actually had the pleasure of visiting the Disneyland Resort on his birthday last year, which was so much fun.
Last year for this special day, Guests were given complimentary Happy Birthday Mickey buttons at the entrance gates while supplies lasted. There was also a celebratory parade honoring the big cheese himself with some of his pals in Disneyland Park. Merchandise was available in the parks as well as the Downtown Disney District to commemorate this special day, and there were also limited time Disney PhotoPass props available in select locations. One of my favorite pictures from this day was holding up a Happy Birthday Mickey sign so I could always remember I was there for this unique occasion.
Since this coming year is even more special being a milestone birthday, I wouldn't be surprised if some extra special experiences are planned. I recommend keeping an eye on the
Disney Parks Blog as your trip approaches for any announcements about this day as it will be celebrated in every Disney Park in the world!
See ya real soon!
