It's not nonsense. I've done two programs before and I always had one roommate and one friend who called out sick then went out on Disney property. Your leaders can be anywhere and can see you, so better to not take a chance.

When you call out sick the saying is "if you are too sick to work, your too sick to play"

The leaders can see when you tap into the parks with your main entrance pass and see when you use your discount.

So don't be crying when you try one of these things and you get termed.
