Hello Jenny! Welcome to the Disney Parks Moms Panel.
When I visited the Magic Kingdom in July,
many stores were already adorned with advertisements and merchandise to celebrate the upcoming release of Disney's Christopher Robin. The merchandise offered included the plush toys of Winnie the Pooh and a few of the characters from the Hundred Acre Wood.
On the
Disney Store website for Disney's Christopher Robin, only the Kanga and Roo plush are still available for purchase and delivery. Estimating whether or not any stock will still be available when you visit is hard to foresee.
Guests from the United States can use the
Shop Disney Parks Mobile App available for smart devices, however, since you reside in the United Kingdom, you may have the same difficulty accessing the App as I do in Canada. The Shop Disney Parks Mobile App is able to search all of Walt Disney World Resort for stock of Disney Merchandise which would quickly reveal the availability and location of any Disney\s Christopher Robin Plush Toys on the property.
If you are unable to use the Shop Disney Parks App, I recommend that you speak with a Cast Member at one of the first stores you visit during your vacation and ask them to use the resources at their disposal to find your merchandise.
If there are any available, a cast Member can easily search for them.
One of my first stops would be to try my luck at
Hundred Acre Goods in Magic Kingdom. Hopefully, a store that specializes in Winnie the Pooh merchandise can help you complete your set.
Good Luck!
