First of all, if you are expecting some elaborate street car ride, this isn't that type of ride. The Red Car Trolley goes up and down the main street of California Adventures "1950's" area. It is just a fun way to see everything without worrying about walking into someone/something and to imagine what it was like when people got around this way.

The Red Car trolley was fun in its own way but it doesn't go all that far and is no faster - in fact, I think it is slower - than walking. Fun to try if it happens to be available as you are passing one of the stops but not worth making an extra effort for unless you have a particular interest in trollers.
