Hello, Devlien,
Congratulations! How wonderful that you are planning to surprise your wife with a gender reveal at the
Magic Kingdom! I think it will be such a magical moment and surely one you will never forget. My first thought is you could stop by the The Chapeau on Main Street USA to purchase Mickey Ears in pink or blue for the big reveal or purchase an baby boy or baby girl ornament at Ye Olde Christmas Shoppe in Liberty Square (it could even be personalized)! I suspect that if you ask a cast member for help with this, they'd be able to box up your surprise to help make it even more special.
You could also contact the Cake Hotline to request a speciality cake that reveals the gender by calling at least 72 hours in advance to (407) 827-2253. If you'd like something even more grand, you could reach out to
Disney Floral & Gifts for assistance.
Also, there are some independent websites that help with surprises and Disney merchandise that may be another option for you: giftsofalifetime.com and pixiedustdelivery.com. I have used both of these businesses and was very happy with their service.
Wishing you a very special day this March! If we can help with any further questions, please let us know. -
