Perhaps a few lesser-known professionals with pleasant attitudes would be a better choice. Prior to selecting a professional, consider finding a corporation to pay the celebrity's fees. Offer advertising opportunities within all tournament-related materials in return. Play begins, perhaps with a box lunch and a roaming beverage cart, and culminates with an awards banquet in the early evening. If the event is a golfathon, the golf clinic could be omitted to allow more time for play.
Some events even have activities for non golfers who wish to watch portions of the event.
Awards banquets offer additional fundraising opportunities. A variety of themes can be used, from labor-intensive casino nights to raffles or silent auctions. If a celebrity is used, perhaps autographed memorabilia can be involved. If not, consider other local celebrities who may donate similar items, or solicit merchandise or in-kind donations from specialty stores or travel agents. Anything to expedite play will be appreciated by both the players and the benefiting charity.
