Okay, maybe the jokes are corny and the songs co-opted. It didn't matter, we had a great time. This is good family fun, and ideal if a full in-depth four hour tour is too much for your interest level. You get a nice, simple overview of Salt Lake City, presented in a very entertaining way by actors in costume.
There are about three stops where you get out for photo opportunities and you do get a chance to go inside the state capitol building (very impressive).
While the trolley won't win any prizes for seating comfort, it was okay for this tour and the air conditioning was very good.
We had a four year old in our group and he loved it. Your family will, too.
