There is a wide variety of sightseeing bus tours across the United States. The Gray Line tour in New York City allows passengers to hop on and off in different neighborhoods at their pleasure. Another type of tour is the Monterey Bay Scenic Tour, which is a non-stop, 3-hour bus ride along the Californian coast. Starline Tours of Los Angeles is another sightseeing tour that provides free pickup from most major hotels; it gives tourists the opportunity to see celebrity Hollywood homes.
Sightseeing bus tours can take as little or as long as you like. For major cities such as New York City or Washington D.C., sightseers have the opportunity to make their own schedules and leisurely explore each neighborhood with hop-on-hop-off tours, such as what the Gray Line offers. Other companies--such as the Starline Tours--have stricter schedules.
Tourists can have very different experiences on tours because of the different types of vehicles used while sightseeing. Double-decker buses are often used in major city centers, so passengers can either sit downstairs and inside, or upstairs outside. Other places, such as Boston, use amphibious vehicles that tour the city streets, and then make their way into the Charles River.
