Although golf might be cancelled for your Member-Guest everyone can still have fun! Arrange ahead of time for a specific time for everyone to show up for lunch. This should be put on the Invitation so there is no last minute phone calls and emails. "In event of rain please arrive at 12 noon for lunch and prizes."
First, when everyone arrives have them fill out three pieces of paper for the drawings."Members" are put in one container and "Guests" go in another container and their combined names as the Member& Guest team. Next, have members and their guest have a little putting contest, or golf ball toss just for fun. Then proceed into lunch and let the fun awards begin.
After lunch start awarding prizes just as though the tournament took place. Build excitement about each award. For example, draw a name for the winner of the Member's Longest Drive-make up a number and award the gift. Continue awarding the team prizes and the individual prizes by drawing names from the appropriate containers. Everyone can join in on the fun. People who seldom win love getting Longest Drive or Low Gross. There are lots of laughs, and bragging rights at the end of the day.
