A fresh point of view can transform the way you perceive everyday sights, like how hurtling toward the earth while strapped to a malfunctioning parachute makes people look like sharp spikes. Safely see the world with today's Groupon: for $17, you get an adult ticket for an all-day hop-on, hop-off double-decker city tour from Starline Tours (a $35 value).

Offering four different loops that travel through Hollywood, Beverly Hills, Santa Monica, and downtown Los Angeles, Starline Tours facilitates city exploration for locals and tourists with its fleet of bright red, double-decker buses. An adult ticket for the Hop-On, Hop-Off Double-Decker Fun Tour is valid for a full 24 hours of on- and off-hopping at any of the more than 50 stops scattered across this map. As a pre-recorded voice points out landmarks, riders can see sights such as Paramount Studios, the Santa Monica Pier, Little Tokyo, and Marilyn Monroe's gravesite.

Throughout the day, customers can disembark at any stop to feed their stomachs, shop for souvenirs, indulge curious minds, or satisfy the compulsion to repeatedly get on and off of buses. All tours run seven days a week; customers can redeem their Groupon for a voucher at Starline's kiosk in front of Grauman's Chinese Theatre (Red Route stop #1).

Reviews

Frommer's featured the company, and AirTran's inflight magazine, Go profiled Starline's Elham Jazab as part of its "10 Best Tour Guides in the Country" feature. Although reviewers' experiences have been mixed, customers agree that Starline Tours is a fun way to explore and see Los Angeles. More than 100 TripAdvisors give it an average of four owl eyes. Yelpers rate it an average of three stars:

• The tour is very informative as it gives you a bit of history about each attraction, and gives you a birds-eye view of the city. – NancyToronto, TripAdvisor
• The fact that the service lets you get on and off the bus at many different stops around the city was very helpful... – PirateFrank63, TripAdvisor
