Good: You can bring your own drinks, the bus ride is pretty crazy, and it is a novelty for sure - great if you're getting bored of the standard "night out".
Bad: 1. The bus is really really hot. 2. Our group chartered the bus, but it broke down several miles from our cars. After sitting there for about an hour they announced we weren't going anywhere. So they gave us back our bus fare and that was that.
The result: Our group got on our cell phones and ordered a mess of taxis, which we paid for ourselves. We went back to Scottsdale - we still had a good time, and we enjoyed the bus while it was working. But we weren't happy with just being left to fend for ourselves and having to pay our own way back to our cars.
