Museums all across the Five Boroughs are taking liberties with their hours, access and events by remaining open late and drawing vibrant crowds long after 5 pm. Have you ever wondered what it would be like to dance at The Guggenheim? Or sip a cocktail at the Met? Indulge your inner fantasy of exploring a cavernous museum at night and check out these New York City offerings.
