The Deuce

Here is the link to the official site for "The Deuce" which is the double decker buses that travel up and down the strip. During slow traffic times taking the Deuce is a cheap way to see the strip. During Rush hour it can take well over an hour to travel from Mandalay to Venetian (I know from experience unfortunately) Anyway, the site has tours of teh doubledecker buses, route info, fare info, and an interactive route map.
