How did John Wilkes Booth get access to Lincoln's podium?

When Abraham Lincoln was assassinated, there were two main reasons John Wilkes Booth was able to assassinate Lincoln who was president and had a bodyguard because Lincoln had given the bodyguard a break. The bodyguard was next door during part of the play which gave John Wilkes Booth access to the balcony where Lincoln was watching the play.

Also, John Wilkes Booth was a famous actor who acted frequently at the Ford Theater. So, it was not unusual to see Booth around the theater even if he wasn’t in the play. He also knew the theater well. He probably had free access to the theater. If someone saw Booth wandering around the theater even if it was close to Lincoln’s balcony, no one would think it was unusual.
