Yeah, you can get termed for the most ridiculous stuff, but in a way, most of it makes sense. They tel you what you can and can't do, and it's not *that* hard to follow the rules. For a CP to get termed two days before, like your example, I can pretty much assure you there was something going on. If Disney really doesn't want you, they can just put you on a rehire list, which the managers are allowed to recommend. I'm betting you guys just don't know the whole story.
As for the girl, when you come aboard, they tell you straight away, if you are gone for 10+ work days in a row, you will be let go, even with a doctors note. It's not quite the same as getting termed if you're sick, you're just let go, with a note on your file saying why, so there is no recourse if you decide to apply again. In some cases, they'll let the person come back, but not many. Honestly, it's not exactly unfair of them to do that. If you can't come to work for over a third of one month, they're still letting you live in cheap housing, and you get the benefits. Disney does have modified duty, so if you get hurt, that's not a problem, but actually sick sick? If you're that sick for that long, it really is in the companies best interest to let you go. Can you blame them for that?
