We were visiting from Canada and were looking for a good way to get around the city while learning some information about the area. We stayed in Santa Monica and took both the blue line and red line around the city. Our guide Frank and driver Anthony were fantastic. Frank was very knowledgeable and offered a lot of interesting facts and history about the area. He catered to his audience and made the tour a lot of fun. If you are planning on doing both loops, there is not a lot of time to hop on and off and catch the last bus back. However, if you have a plan of where you want to go, it works great. I would recommend this tour.
