I am visiting Los Angeles for the first time, I am only going to be there for a long weekend. I am interested in taking a tour of the city. I am interested in seeing the Hollywood sign, Graumans Chinese Theater and other Historical landmarks. I am less interested in seeing movie stars homes. I also wanted to take a tour of one of the movie studios, the Warner Bros. VIP tour seems interesting. I am open to suggestions, there are so many companies I am trying to find the best one for a decent price.
