I wholeheartedly agree. I'm so fed up with people complaining about parking fees.
If the parking fees were eliminated, they'd just jack the prices up by $200 per team, and nobody could avoid it. ...
You are close. The average team is good for about 12-13 cars, depending on age group and gender (13 year old girls teams are the best). The average number of games during day-light savings is 6-9 depending on age group. If we were to eliminate parking, then the facility clients (leagues, tournaments, clubs) would pay about triple for fields. Take for example a 100 team tournament, the daily parking expectation would be roughly 12,500 per day or $25k over a weekend. The tournament would pay roughly $8,000 for the fields per day. So if we stripped that $25k from the facility the tournament operator would pay $41k for the fields, instead of $16k. That $25k divided between 100 teams, which would be $250 per team so your $200 is fairly close.
