Too costly. Not enough return. And much of that can be handled online without leaving home now.
You are looking at it wrong (in my opinion)
there is a ton of ROI that is currently untouched.
Go to a bass pro they are hammering their time share program near the door. While disney would want to soften that approach, they could easily have a third part travel agency/dvc/ concierge that works partly on commission in an area of the store.
Store exclusives- funko pops, keys, plushes that are only available at the stores
Birthday parties (something toys r us should have done),
Selling Disney+
Movie previews for whatever new is coming (some of the disney stores used to have big screens in an alcove that showed disney cartoons)
photo ops for instagram
pin trading
So you would go there for an over the top disney experience for the addicts (us), the kids, the people who have never been. You can have your birthday party there, you can get special ears and a funko thats only available there, there are statues and animatronics in a well themed store.
ROI-more pixie dust, dvc sales, trip sales, instagrammers, collectors, disney +, the next movie, birthday parties, and MERCH
make it a disney experience with amazing cast members handing out stickers and buttons (for no reason just to be nice)
to keep costs down, maybe some of these things are just open on the weekend and during the week its just a fun store.
It wont hurt the parks at all, because there isnt the same magic, no castle, and no rides. But it will hold over everyone till they can go, or make someone decide they have to go.
I relate it to how the original disney tv show was (besides a way to pay for the park), a way to publicize the parks.
