This is a state/tax issue. The hotels are simply following the appropriate tax laws. Last year I lived in North Carolina and lived in several hotels during that time that I was looking for a place.

Staying more than 30 days and you run into tax and residency laws. Also, if you're going to stay at *wood properties anyway then they haven't lost you as a customer, gotten you angry enough to lose your $ (or your wife's) business, so. . .playing "devil's advocate" why would they do anything for you (although I agree it's the "right thing" to do or at least give you partial credit)?
