The Deuce!
This double decker bus takes you from the Strip to the Downtown area, and all points in between. The bus is air conditioned, and has free Wifi. The bus here is a lot more expensive than the other public transits I've taken in other cities. Even NYC isn't this expensive for the bus. But they offer a 24 hour ticket that pays for itself at three rides. The 24 hrs is a running clock, not calendar, so that's helpful.
The buses run 24 hours a day, and there's stops everywhere.
The problem with this bus is that it takes forever to get anywhere. It was about a 45 min drive to get downtown. They stop at every podunk stop along the way. It'd be nice if they had an express option.
There aren't any bathrooms on the bus. Don't drop a deuce.
