This is a Halloween season tradition for us! You're going to have so much fun! There is usually a little exhibit downstairs in the theatre with props from the movie, so be sure to check while you are there.
Across the street from the El Capitan is the Hollywood & Highland shopping center where you can see the Dolby Theatre (home of the Academy Awards ceremony), the Hollywood sign (photo op on an upper level), Chinese Theatre next door, Walk of Fame out front (in front of the El Capitan and the H&H center), etc. Sometimes El Capitan tickets have a coupon for $1 off a sundae at Ghirardelli next door. Have a great time!
