You know a city has made it as a tourist destination when it gets its own hop-on, hop-off open-top sightseeing bus. The Doha version ranges from the Marriott Hotel south of the city centre and goes all the way to the new Pearl development in the north. The journey takes 2½ hours. Tickets cost 10% less if you book online.
Major stops include the Museum of Islamic Art, Souq Waqif, City Center Mall, Katara and the Pearl. Buses pass every 45 minutes, and if you've bought your ticket online and can't print it, there are kiosks at Souq Watif and City Centre mall where you can pick up your ticket.
