The minimum cost to hold a national would be the same if 10 people attended or 1,000 people. The difference is if it is underattended, the club would lose money. ACA guaranteed the hotel that it would sell a minimum of 635 rooms, $75,565, and $12,000 plus gratuity in food/beverage sales, bringing the minimum required to almost $90,000. Without member support, the minimum would not be reached, and ACA would have to pay the difference to the hotel.
