You are asking for a big brother approach you realize. A top down government decree micro managing the entire hotel industry and ensuing bureaucracy. Why you ask?

Quite simply the first chain to raise prices and hit "you" in the pocket will see "you" going the the other hotel that does not have the laundry charge.

Yes. Yes, I am. I'm asking for a Big Brother who is more mature than NASCAR Joe Sixpack to tell him not to stay in hotels or to travel when he doesn't need to.
I don't see why this would involve the government, though. Simply actual leadership by the hotel owners (and their associations who fix the prices....yes they do). As with all business groups or corporations that CLAIM to be members of the community, they should be taking on responsibilities to improve the world wherever they can that doesn't drastically affect staying in business. Leadership sells. Government leadership, doubly so, but I dare you to find some and prove it.
