We did a little research ahead of time because of the large number of companies that sponsor these types of tours. This one had enough good reviewed, we went with it.
We had low expectations and expected it to be sufficiently cheesy. What we didn't expect was how much fun we would have. Shay was hilarious. Not canned and predictable humor, but just ad hoc funniness about people on the street or sitting in cafes, or driving by in their cars. He was a hoot and had my teenagers entertained the whole time, but not in that over the top way.
The ride was comfortable and we saw the beautiful Hollywood hills, Beverly Hills and some other areas. I would recommend it. It was a nice break from walking around and just something you have to do.
