Disney says husband can’t sue over wife’s wrongful death – because he signed up to Disney+ trial

If the resturant was not Disney owned, that resturant would be mostly at fault, but if the resturant is inside Disney, i am sure they have to follow Disney protocols, and if Disney failed to regulate them properly, Disney does share some responsibility. When you eat somehwere inside of Disney, you assume its Disney owned, i am sure they want it to be assumed that way..
I am sure complacency played a big factor in this.

I dont think Disney takes on liability for every third-party vendors operating on Disney property - that would be highly undesirable and it’s just not necessary. That’s not the default legal result so why would Disney create that exposure by highly regulating each vendor to the extent that Disney takes on responsibility?

That would have to be created in the agreement between Disney and the vendor and I just doubt that Disney is agreeing to that level of inspection and regulation of the restaurant.
