The only thing I've heard is that honeymooners sometimes get upgraded. However I am honeymooning at the Poly in July, so I think people have gone out of their way to tell me about their honeymooning experiences...that's why I've heard so much about it.
I'm sure Disney just does it whenever the situation presents itself, and the CM has the urge to do an upgrade that's available. It's probably rare & happens to lucky people.
I have not had an upgrade since 2004 at WL. Now i have no choice but to book courtyard views.
