Hello Kathryn!
I can totally relate! I have an adorable 5-year-old daughter who also adores Mal, Evie and the rest of the Disney Descendants. We've read all the books together, watched the movies and sang all the songs countless times.
It's hard to say just if or where you'll have the best chance of finding Disney Descendants merchandise next fall. What I can do is share with you the magic of the
Shop Disney Parks Mobile App. When I'm in the parks, or even when I'm home, and I'm trying to find a special item I use this App to see exactly where it's located. You can search Disney Descendants and pull up items that are available throughout the
Walt Disney World Resort. If you see something you like you can select it and use the "Find on Map" feature to see exactly which locations have it. I found a sweatshirt I loved on my last visit, but finding my size proved difficult. With the Shop Disney Parks App I was able to view it and know just which store we needed to visit so I could bring it home.
Have a wonderful vacation, Kathryn, and please let us know if there is anything else we are able to assist you with.
Magical Wishes,
Lauren
