It wasn't on our list, but using the hop-on-hop-off bus, we got the free entrance with the bus tickets. It is a bit complicated that the tours a time-dependent so you can't get inside when it is suitable for you, but you got to wait for a certain period that they will share when you get there. However, the tour itself was interesting, history, stars, old-time Holywood glamour, lots of fun facts, unfortunately, we could not hear well what the guide was saying as the sound from the movie projection was extremely loud. It is a short tour, but it wasn't a waste of time. If you happen to be there, I would recommend the visit
