NO!!! We were on the Mercury 6/1 Alaska and on formal nite our table of 4 couples consisted of 2 men in tuxes (hubby and 1 guy without tie or cumerbund), 1 sports jacket and 1 guy in a knit shirt and sweater. Until the line has the willingness to refuse dining room admitance to anyone not willing to wear a dress shirt and tie on a formal nite they can NOT be considered upscale. Also, the dinner menus were no better than our Carnival cruise 12/01 and they charged for expresso and cappachino in the dine room which Carnival and even NCL did not. I am highly disappointed in Celebrity. The staff was basically acceptable although we did have problems. Nothing outstanding however, and our tips reflected that.
