Your call, man. But here's the reality of the situation and the reason that you are so worked up:
(To borrow from your original post)
"So this morning, I change my plans radically" - This is your fault.
"Drive in to Seattle" - Your decision.
"Battle traffic" - Not your fault, I suppose, but more yours than Jeep's
"Battle parking" Same as the above.
"Buy the ticket" - Your decision. You knew that the auto show wasn't free.
"and wander all over the hall trying to find Jeep. After about 15 minutes of wandering, I finally spot them over in a back corner." - That is their fault. It's a shame you had to walk so far.
"I go through major hassles and waste $24 to see one car" - Again, that is your choice. You chose the hassles and agreed to the ticket price.
"I've had it with Jeep. The Cherokee is off my list. It's obvious that they don't know how to run their company." - Wait, what? What a drastic turnaround. Suddenly it is Jeep's fault.
I'm not trying to belittle your situation. I would also be pissed if I did all that and didn't get to sit in it when I assumed I would. And sure, we'll say it's about Jeep and not the Cherokee. But you are now basing your whole opinion of the company off of a few comments on a forum and this one experience that was, let's face it, mostly your own fault.
As others have said, this is not exactly a new thing at auto shows. You can go in most cars, but there are always a few that you can't. It is unfortunate that this happened to you, but saying that Jeep does not know how to run a mutli-million dollar company because they did something that other car companies have also done is just, well, amazing.
Again, not trying to make this an argument, and I hope you're not offended by any of this. Just trying to point out a few things.
