My wife and I will be in Paris Sept. 24 to Oct 1. We have booked tickets on line at L'Olympia for the Jimmy Buffett concert 9/26. (OK no snarky comments. Wife loves him and its our 25th anniversary return trip to Paris.) We have cat 3 orchestre "seats". My question is are these actually seats or are we in a standing room only area? No seat numbers appear on our order confirmation. One review of L'Olympia on TA noted that the seats have no numbers but the tickes do. Festival seating? I ask this because we went to see BB King at the House of Blues in Cleveland and were in the standing room only section. We knew this ahead of time but we were standing for 4.5 hours. We just want to be prepared if we are going to have a long night on our feet. Thanks for your input. I have enjoyed reading all the advice from the expert posters over the past few months as we prepare for our trip.
