The ticket is valid for two days, but I could have completed the tour in one. It's divided into two main sections: one for ancient buildings and one for buildings from the Republican era. There are performances and interactive NPC games, but not many. I heard there were light shows and other performances at night, but it rained so I didn't go. I'm not sure if they were on schedule. I've been to quite a few film and television studios, and overall, I'm pretty happy with them.
