I'm trying to figure out how much time to allow for touring Hollywood. The things we definitely want to get in are: 1) lunch at Pinks Hot Dogs, 2) tour of Grauman's Chinese Theater; 3) view some of the Walk of Fame; 4) shopping on Melrose Ave. If we have time, we'll do Madame Toussands Wax Musuem - but that is not a must. If I allow 4 hours for this, is this too much time? Not enough time?
