We’ve used hop-on hop-off tour buses in many places (for example: London, York, Dublin, Dubai, New York), and it is a useful way to get your bearings in a new city.
This particular tour was not well advertised or signposted. For example, on the brochure it shows that there is a scheduled stop behind the Luxor; we waited there for more than 30 minutes but nothing went past. We also asked at one tourist information office on the Strip where the nearest bus stop was, but they had never heard of it. Eventually we found it by the Hawaiian market.
The buses were nearly empty. On the blue bus there was only us and the tour guide.
The routes could be merged and simplified. Maybe they can do some analysis of their most popular pickup places, or maybe do some market research. From our side it seemed that the blue bus route could easily be combined with the red. The blue route really only needs to stop at the Stratosphere, Fremont street, and the shopping outlet, with a driveby of the Elvis wedding chapels. Otherwise it is seemingly 90 minutes of driving through dull sidestreets, past signs for bail bondsmen, and graffiti.
The top seats offer a good view. Wear sun protection.
