A reasonable person would think the EULA clickthrough on their set-top box to watch Disney+ might have some impact on consuming media and paying for it. But nobody would imagine that EULA would extend to other Disney products, especially in meatspace.
ALSO if that were true, it means that some park goers did not have Disney+ contracts and they would be under different liability routes than subscribers.
ALSO what if someone bought a DVD or t-shirt with its own license, then does that apply to physical harm at the park?
It seems to a lay person, what happens on the set-top stays on the set top.
