Since most are on the adjacent National Mall, the maps can be particularly helpful for plotting a day of museum-hopping. Docents also man a help desk and distribute printed guides. There’s also a coffee and snack shop and a large seating area with free Wi-Fi, an ideal place to take a break and plan your next move, be it bug-viewing at the National Museum of Natural History or a dip into contemporary art the Hirshhorn Museum and Sculpture Garden.
