I don’t think that Toy Story as a property is completely useless as a themed environment. As an example, I think that the third track version of the load room (I think it’s the design from Tokyo?) in Toy Story Mania is a beautifully designed, transportive area with a lot of nice touches. Entering through the giant door, starting the ride by going under the bed into the game’s box, leaving under a side table, and so on. I really do feel like the size of a toy in that room.
It works far better than the two track version, which feels a lot more like a loading area than Andy’s room. I have a feeling the same principle will be applied when our “backyard” opens as compared to the other versions.
As time goes on, I’m of the mind that maybe a Mermaid Lagoon approach would have served the land better. It would’ve been neat to enter Andy’s house and see the Alien Saucers in the hallway, with the Slinky coaster spilling down the stairs as you walk towards Andy’s room to ride Mania.
