My family and I took this tour early this month and we enjoyed it. The five hours went by really fast. We saw exteriors for many old and newer movies/TV shows. ("Gilmore Girls" was mentioned often; it's too bad we'd never seen that show!) Going on the set of the police station from "Cold Case" was my favorite part. We also watched as "The Mentalist" filmed exterior shots.
Of course, shooting schedules determine what you'll see on the tour. Our guide did say, however, that the upcoming months typically are the busiest.
We usually don't spend that kind of money for a one-day deal, but, in this case, we thought the tour was worth it. (Lunch was good, too.)
