For example, the Conrad New York's lobby is home to a dramatic, 13-story Sol LeWitt painting titled "Loopy Doopy."

"Art in a hotel is no longer just for decoration," said the Conrad's general manager, Marlene Poynder. "It is now a voice that builds a hotel's identity and sets it apart from the rest."

Alice Gray Stites, 21c Museum's director and chief curator, said, "Today's travelers seek more than just a comfortable bed and warm meal. They are looking for meaningful experiences that connect them to communities and engage them with new ideas. Learning is the new luxury."
