Yes, it's public transportation, and yes you're going to have characters aboard. Nothing different than any other city's light rail system.
Honestly, I had no ultimate destination and strictly wanted to sightsee. Having no idea what to expect, I chose the day pass at $4 and got on at this stop. Yes, they will check your ticket. Mine was scanned three times while I went to and from Phoenix. One girl gave an expired pass to the ticket gentleman (sorry I don't know his correct title) and all he said was "your ticket isn't valid, make sure you get a valid ticket". Well, that was nice.
In the train in the trip into Phoenix, the windows were covered with some sort of dotted barrier, so we couldn't really see out. In the cart back into Tempe, we could see out with no problem, even when it started getting dark. I guess we lucked out. We met this super cool dude that showed us his video collection of train characters that he's encountered, including the window licker. Footage of a guy literally making out with his reflection. You can't make this stuff up.
When we got to the end of the route the announcement indicated that it was time to exit, but we were in for the long haul and stayed on. So, don't pay attention to that announcement if you're site seeing too. read more
