Gray Line New York Sightseeing 
Gray Line's double-decker buses and deluxe motor coaches are tried-and-true ways to see NYC's essential sites. All expeditions last at least two hours, and visitors may choose among downtown, uptown, nighttime and Brooklyn loops. Those who don't want to pick just one option may be interested in the 48- or 72-hour All Loops Tour, which includes hop-on, hop-off rides on all four tours, or the All Loops Tour with access to attractions like the Top of the Rock Observation Deck or The Museum of Modern Art. Gray Line stops include Chinatown, the Apollo Theater, the Brooklyn Botanic Garden and Lincoln Center. International visitors can also take advantage of tours in German, French, Italian, Spanish and Portuguese.
