Disney D23 is helping members to celebrate Mickey’s milestone birthday this year with party kits. There was a sign up period earlier this year for kits and discount codes to share with your friends/family so they can join D23 and save $5 on membership the first year for your guest and based on how many people use your code you received a reward too. (Speaking of which if anyone is interested in joining and wants to save drop me an email or direct message and I can share my code). I signed up late and it said the kits were gone and they would email me links and codes. Then in the mail I received a box and inside was a kit.
In addition to the kits D23 has a website (https://d23.com/party/) with items to help you plan your own party including items to print out, recipes and other ideas.
