I love The Metropolitan Museum of Art any day of the week - though weekdays more, any season - though spring is my favorite. People always think they will see all there is to see here in one day. I can promise you that it's not possible. I mean, you can walk through it in one day, but you won't see everything. I would say at least two. And that's only if you don't detour for two long at their wine bar, or lose track of time at their rooftop cafe and martini bar - which by the way, makes for a great sunset spot. And even still...you'll definitely need a lot of time to explore.
