Yep, there are a number of variables.

If I recall correctly, the orchestra pit at the Majestic does not have any
forced air circulation. All that occurs is via the pit opening in the apron
and through a door at the rear of the pit that opens into the crossover
corridor.

The crossover has no forced air circulation either - just a door to stairs
going up at each end.
