Yes, you can certainly walk Hollywood Blvd. alone and see these sights but it would be minus all the trivia and interesting facts that accompany this guided tour. If left to my own, I would have walked briskly through the streets, annoyed at the vendors and taken in maybe 10% of the experience. Instead, our guide offered little tidbits of history and nuances that I never would have been privy to. Donning the headphones and following a guide through the maze of Hollywood is a tour not to be missed.
