Is anyone else worried that if you change promos and the CS person is scoring your stays by hand, he/she might not allow stays where you paid only $2 to the visa? Or might it work the other way, where they will be even more generous? Or maybe it doesn't matter because it's all automated?

Another question: In theory, one could switch between earning miles and earning points and thus play both promos (megabonus and more miles), right? Of course, I realize that any given stay will only work for one or the other.
