It's just so expensive for what it is. You can hop on and off all day, but realistically most people would only want to go round once. The drivers are great and informative, but $40! The only stop I actually wanted to get off at was the southern most point, this is only 1.4 miles from the main strip so easily walkable. The rest of the tour is a nice enough drive around but there's really nothing to see that's worth $40 per person. It's a decent tour and if it was $20 I'd give it 4 out of 5.
