We want to go see a concert at La Madeleine. The last time we did that, we made a reservation on line well in advance, because we thought that it would "sell out." We made the reservation and then were told that we should pay when we arrived at the concert.
When we arrived, I tried to give someone my name and the printed reservation sheet, and was told that I could just buy tickets and that the reservation, and the piece of paper were really not needed.
So, this time, I'm trying to figure out if I should just "show up" or if I should make a reservation in advance.
Can you help?
