I've also had quite good luck in Radisson SAS Langsheng hotel in Shanghai. Twice I was upgraded to a business category room with our a nego price of 60 euros. It was just showing up the SK*S card and being firm that we have these priviledges. ^ The whole floor carpets were just amazingly nice texturized and the view... Once I even got a coupon for a Tsing Tao beer in lobby bar.
