People with no traffic problems always think shows can be any length...lol.
Jim has it correct. Many replies, many answers.
Gil is also correct. I have a 40 car parking lot that we face the show towards. Over the years we have had 6 songs (last year), 14 songs (the year before) and 12 for a couple years before that. That is approximately 18 minutes, 42 minutes, and 36 minutes respectively.
With no traffic problems (we are on a park road, with entrance on one end and exit on the other of the parking lot), people usually stay until they see a song that they have already seen. A few leave before it has gone through the complete cycle, and even more stay through several cycles (not counting the cars with fogged up windows).
Note that last year's show was the shortest. (We rebuilt the whole show, didn't get as many sequenced as I wanted to.)
"Exit Polling" found that they were all satisfied and told their friends. (The car count last year was unbelievable for a small town show.)
