I've asked this ?? before, but just trying to get a handle on it. Been to the Vatican a few times, but more than 10 years ago. We just walked right into the Basilica without any lines or waiting. I'm going in Sept. and I'm hearing of long lines and waits just to get in the church. We are not going to do the museum or Sistine Chapel. Do I need to buy tickets to get in and to avoid the wait in lines as I know entrance is free?
