Hi there, Rob!
Thanks for stopping by the Disney Parks Moms Panel with your great question. With so much amazing merchandise available at the Disney Parks, I always have such a hard time deciding what I'm going to buy!
Although you can't specifically order merchandise from a park without entry, I do have some advice for ways to find just what you are looking for. Many Disney Parks items are actually available on
shopDisney.com as well as the Shop Disney Parks mobile app. I always check both of these as the selection is slightly different between the two. If you are in the parks or World of Disney at Disney Springs, you can always ask a Cast Member to see if an item is available somewhere else. Even more helpful is if you took a picture of the item's tag. Apart from the parks and Disney Springs, there is also great shopping available in each Walt Disney World Resort Hotel. Once I was on the hunt for a very specific sweatshirt I saw in Disney's Hollywood Studios, but it wasn't available in my size, and the Cast Member let me know that this was actually available at Disney's Contemporary Resort gift shop, Bayview Gifts. I used this opportunity to check out this iconic hotel as well as grab a mouth-watering cupcake from Contempo Cafe when I went to purchase my sweatshirt.
I hope this helps, and please return if you have any other questions. I hope your trip is practically perfect in every way!
