If you park at the Hollywood & Highland shopping center, you can see the Walk of Fame right out front, the Chinese Theater next door, Disney's El Capitan Theatre across the street, and the Hollywood sign (from the viewing area on the 3rd level, I think, of H&H) and the Dolby Theater (site of the Oscars ceremony). If you still want a bus tour, you can ask for info and buy tickets at the guest services desk at H&H. Also, you can get a parking validation at the guest services desk or at any shop/restaurant.
