A fantastic way to tour the old city. I really like how the pass is good for 3 consecutive days; unlimited on-off access to the trolley with free parking at designated trolley stations. The trolleys are not busy during the week, but got PACKED once the weekend came. Also price seemed a bit steep at $22 or $23, I can't remember exactly. But the trolley drivers are nice and they give a good narration while you ride. The free museum admission is kind of lame.
