Fascinating article listing all the problems Disneyland had on opening day, July 17, 1955:

Wow.  Just…wow.

I recall going to Epcot very early on after its formal opening.  My memory isn’t exact but I believe it was within a month or two after the actual opening, and I found the whole thing so underwhelming.  In part, and again, if my memory serves me (it can be off here), I recall there many rides that were either closed or not opened yet.  The whole thing seemed to me like it opened too early.

It annoyed me, along with all those corporate sponsorships of each ride.  But nothing like all the problems listed above!

Ah well, just goes to show, when you open/run a business things aren’t always going to operate super-smoothly.  The trick is in addressing/fixing your problems as quickly as you can to make the experience better.

As they say, thank you Captain Obvious!
