As they have done before when attendance has been down, the Opry is offering a buy 1, get 1 free on Opry tickets. You have to purchase your tickets by Sunday and the offer is good on any show through April 30. At this point, the offer is not listed on the website and must have been sent to people on their email list.
When you read the small print, price level one tickets do not count, so it looks like they are trying to fill seats in the back corners and the balcony and there are possible blackout dates. Which means if Carrie Underwood is coming, the offer does not apply on those dates.
Maybe instead of offering free tickets when you buy one, they should cut ticket prices, especially during the off times when attendance is low, and more people could afford to come to the Opry, or be inclined to buy tickets.
This past weekend when I was there, I would estimate the attendance at the Friday show at around 1500 and on the Saturday show, maybe 2500. Lots of empty seats in the upper balcony and the upper wings.
