I simply attended a Sunday Eucharist. They do have tours but I didn't do that. I was there in June 2017. They are still doing work on the building from earthquake damage a few years ago. Very informative.
For Christmas service, we had to go online. Small fee, I guess to control numbers so everyone gets a seat.
You do not need a pass unless they have a different system because of Christmas
This year we went 2 days before Christmas to sit and enjoy the choir practice with very very few people around.
