At the beginning of each week, check a game later than yours time-wise (Monday night being the best choice so after you play your game, the week doesn't end). Before playing your game, go to Owner's Box and max out money on all advertising. Play your game and you'll receive the attendence for the max advertising. When your game is over, go back to Owner's Box and drop all advertising to $0. Go back to Play Week, uncheck the checked game and simulate the rest of the week. When you go back to Owner's Box and check your balance sheet, the amount of overall spending for attendance will stay the same, but you'll recieve the attendance boost.
