This brings up an interesting question I think.
Historically what percentage of on property restaurants have been 3rd party?
As Evan said, most people would never know Hacienda was not Disney owned, and I am sure that is the case for most guests, and most 3rd party restaurants currently operating on property. And without the internet shrinking the world, and offering up this kind of information, how many of us would even be aware of these 3rd party affiliations?
So, it stands to reason, maybe a large number of restaurants have always been 3rd property, and we just did not know.
So, Martin?, any answers on this subject? Has WDW always had a large percentage of 3rd party restaurants?
