The one difference is that there were a lot more people that drank Coke then attend WDW on any given day. Also the taste of Coke is somewhat unique and people remember it. It is a singular memory! The majority of guests at WDW only vaguely remember what they saw the last time they were there, if they have been there at all.
OK.....
Coke is an integral part of American life.
I submit that Disney is also.
But each person drinking Coke likely spent less than a buck a day on the product back then.
About $350.00 a year if you were a hardcore Coca Cola fan.
As I recall Coca Cola lost millions in just 77 days because of the dislike for their New Coke.
A substantial amount back then.
Disney visitors can easily spend $250.00 per day, per person, to enjoy the parks and at around 145,000 people on a good day in the four parks that's about 36.25 million dollars per day.
The loss of just 10%, 14,500 people, or 3.62 million dollars a day, or $1,323,125,000 (with a B) per year, is no small potatoes even to Disney.
I submit that the potential exists for at least a 10% drop in attendance if the current wave of cutbacks and value depreciation doesn't stop.
Word is out across America that Iger, et al, have sunk a monstrous amount of money into overruns and waste at the Shanghai park and that the results are cuts in the quality, and scope, of customer experiences at the American parks.
It may not be this quarter, but a drop in attendance is likely this year as a result of the current mismanagement.
I have several corporate investments but
none of them are in Disney or it's subsidiaries.
And I remember our first visit to WDW, and every subsequent one, vividly.
It could be that I'm in the minority for having that ability but somehow I doubt it.

P.S.
Someone should double check my calculations.
It's late and I'm tired......
