It would seem to be that if that is what happened that it would be obvious that it is a pre-existing condition. The question is, if that is do we assume that a pre-existing condition is something that we unquestionably should be aware of? People have cancer for years and until it gets serious do not even know it is there. It doesn't matter if it is water (I can't think of any reason why that is the reaction that would result from that) or not enough solid anchoring that caused a failure. It seems to me that the if it was due to construction problems it would have created that condition at the time of construction and no connection to maintenance. If they used the wrong materials or insufficient anchoring it is something that would require someone with x-ray vision to possibly spot. And I believe that Universal has exclusive rights to that guy east of the Mississippi. It hasn't even been established if there was that much initial damage or if the person had come along with a camera after the crew had removed some of the panels and perhaps didn't neatly stack them up.
I don't think that over 10% of those that "won't go back" are even aware of any random situation such as this much less using that as an excuse for no longer wanting to play in that sandbox.
What makes you think that water leakage had anything at all to do with it?
I agree, and I wasn't quoting anyone anyway. That said, however, is that you have lost the confidence that nothing bad could ever happen at WDW? Seriously, are you close to not going because a random facade came loose? That's no way to live a life. I have lived to 74 by being cautious of things that had a high level of probability of danger to my well being. Not to the trivial things I am not aware of existing.
I have never done things like swim in hand sanitizer and I occasionally lick my fingers when eating fried chicken. I haven't even had a cold in 5 years. I do have other problems but none that I can blame on outside sources. As a kid I drank out of a garden hose, rode many, many miles in cars that didn't even have any seatbelts, went over the speed limit quite often, and as a kid I used to fall asleep up on the back seat window shelf looking up out the rear window at the stars. Nothing about any random, freak situation, such as discussed here that would ever make me stop living and doing the things I like because things aren't perfectly safe. What's the reason for living if we don't live it. We can be a perfectly superb physical specimen and wrap ourselves in bubble wrap and we are still going to die of something. So why obsess over irrational fears.
