I just learned that the annual Museum Mile Festival is scheduled for one of the days I will be in NYC. For those who are familiar with the festival; are the museums too crowded to enjoy, specifically the Met and Guggenheim? Thanks!
As far as the Met is concerned , depending on which galleries interest you , it is a large place , and it is easy to get lost in corners that are sparsely populated . I see that The Neue Galerie is included , and you should not miss it While relatively small , the collection of Austrian and German art is magnificent , and includes Klimt's famous portrait of 1907 " Adele Bloch - Bauer I " aka " The Woman in Gold " - http://www.neuegalerie.org/
The Guggenheim is often crowded. The Met is enormous. At the Met, the French Impressionists will be crowded as will the Temple of Dendur. The American Impressionists however could be delightfully quiet.
Gems of the Museum Mile include the Museum of the City of New York and the Jewish Museum. The Museum of the City of New York has a "suggested admission" which means you can pay ANYTHING you wish. The Jewish Museum has free admission on Saturdays; FYI on that.
