What pass do I need to buy to use both the trolley and bus system for four days. Sort of a hop on/off to get to and fro.

Starting September 2019, there will only be one day passes they will cost $6 a piece. There's the $72 adult bus pass. There has been the $43 half month pass but that will be eliminated starting in September. So will the $10 two-day passes and the four-day passes. I'm pretty bummed out about that

The Day pass. Which is use for any direction of travel trolley or bus.

Go to12th and get a day pass and it will be 5dol. A day

4 day pass .. go to 12th and Imperial store
