My wife and I have stayed at most Park Hyatts in the world (including five that are no longer Park Hyatts - among them are the losses in London and Buenos Aires, the one that is now a Four Seasons). We certainly put those in Tokyo, Paris (Vendome) and Sydney at the top, but would add Chicago, Madrid, and Melbourne as very near that distinguished level. Somewhat below are the Park Hyatts in Johannesburg, Zurich, and Milan. During our last visit to Tokyo, about six months ago, we stayed at the new Grand Hyatt, where we were upgraded to a corner suite. It was a thoroughly enjoyable experience. What the Grand Hyatt lacks in elegance vis-a-vis the Park Hyatt in Tokyo, it makes up for in location and the existence of an impressive RC.
