There is something I forgot to say in my writing about Salzburg. Both the Large Hall and the House for Mozart have really excellent acoustics. I sat in various areas in both rooms and could always hear the singers. I am accustomed to the San Francisco War Memorial Opera House which has truly terrible acoustics, so this was a treat. In its defense I don't think either of the Salzburg houses are as large as the War Memorial. Bad seats. Marvelous acoustics. Perhaps this is the proper prioritization.
