I had made the remark that Paris was a draw for North Americans but was quickly refuted by posters saying that Paris was a hole and the security concerns would likely deter players from coming rather than attract them.
Copenhagen ranks amongst the best cities to live and visit in Europe. Actually the Worlds take place at several fairly significant centers of commerce and culture in Europe, including Vienna, Zurich, Stockholm, Prague and Copenhagen. Short of the likes of Paris, London, Milan and Barcelona, three of which the IIHF will never go to, there aren't any huge famous (to those living across the Atlantic) draws that would be particularly more attractive to an average American/Canadian in Europe than these choices.
If there are no NHLers at the Olympics we might see a slightly stronger roster than usual even. No offense meant to Slovakia, but it's 2019 I'm more worried about. Bratislava usually isn't on anyone's top 20 list of European cities to visit.
