Really great way to explorer the strip and beyond by saving your shoes and not get paranoid fighting the crowd. Deuce and SDX go N and S parallel, with SDX making fewer stops. Deuce is manned with safety guards of and on and has cameras installed everywhere. $8/day or $20/3 days and you can use it all you want. Safe to take at late hours. One may just pick up the best tourist conversations on the bus itself. Ticket machines on nearly every station. Easy to use. Cash or Credit Card. For all phone app junkies. This one has it's own but you don't really need it.
