As Vicki says, you should have spoken up. There is the chance that the hotel thinks of the sixth floor as being a "higher floor" in terms of customer preferences. Personally, I won't stay on a first floor, don't like the second floor, but am fine with anything above that. IMO, there are noise issues on the second floor, and the first floor creeps me out, because I keep thinking people can see in the room and climb through the window. Being away from the ice machine is usually a bigger deal to me than third versus tenth or so floor, but alas, there is no box to check for being away from the ice machine.
I'm sorry to find out that the CL is no longer open on weekends. It is a very narrow CL, I do remember that.
