I ran into an article the other day (from a year or two ago) where Mr. Marriott was speaking of the new beds and the new laundering proceedures. He expected to be able to get about $30 more each night after the changes were implemented. I think we are seeing the price change now. Personally I love the clean comforters - thats worth a lot to me, but on a couple of occasions we have opted for a CY over a full service where we would have NEVER done that in the past.
Edit: We have nothing to do with gov. rates. I was just responding that a $30 increase was announced ages ago as expected to go along with the better bed thing - I would guess that amount (or some percentage of it) is added to all rates as the hotels complete their redo's.
