Well if they want to go through life with their head up their asses who are we to argue? Personally, the less american tourists the better..... I have had some very bad experiences... including one yelling at a shop keeper in germany because he wouldn't accept american dollars...
I haven't been there, But I canadian guy I know says Whistler is for the tourists.. he said his local mountain terrain was just as good, and the tickets were half the price..
