If you go to one museum in New York City, make it the Met. We spent half a day there and it wasn't nearly enough. There is so much to see that it should be a two day experience. I rented an audio guide and it was very helpful to learn about the background of the artists and their paintings. You are allowed to take pictures as long as you don't use the flash. It was a once in a lifetime experience for me to see such wonderful art!
