I did this tour on my own while visiting LA with a friend, because I wanted to see some of the celebrity tours and the city. There is parking close to the pick-up point and you have to wait in the office in the plaza. There are toilets and comfortable chairs ion the office. Everyone is very friendly and chatty. You can take drinks and snacks on the bus and there is a 7-Eleven in the plaza. The buses are for about 12 people and open on the sides, which is great for visibility, but you have to be a bit brazen and ignore locals beeping and shouting abuse at you, because they are unhappy with tourists disturbing rich and tranquil neighbourhoods. I personally did not care and thought it was funny. Once you enter the bus, you get a wireless set of headphones, which makes it easy to understand the tour guide. Our guide was friendly and informative, although I did not really get or share her sense of humour and she digressed quite a lot. It did not matter much, since the tour itself is interesting and beautiful, taking you through the Hollywood Hills and along Mulholland Drive, then into Beverly Hills and along Rodeo Drive and the Sunset Strip. You get to see a ton of celebrity homes (Gwen Stefani, Justin Timberlake, Lady Gaga, Marilyn Monroe, P Diddy, Michael Jackson, Elvis, Kardashians, Ellen Degeneres, Adele, David Lynch, John Legend and many, many more) and learn a lot about the different neighbourhoods. You can interact with the tour guide and let them know if there is a particular celebrity you are interested in, etc. We stopped once at a nice lookout and had 5 min to walk around and take pictures of the Hollywood Sign in the distance and the Downtown area. Overall, I would recommend this tour. It's not cheap, but you get a great 2-2:30 hour tour of LA and see some beautiful celebrity home. It's worth noting that this is NOT a celebrity spotting tour or "safari" - it is mainly about driving through areas in which celebrities (and other very rich people) live and visiting some of the fancy and more glamorous areas of LA.
