Oh, the power of a good cup of coffee!
To encourage help with getting things set up, we incorporated a coffee hour. We ask those who can to come early and get things ready and have coffee and special treats for everyone who helps.
I always make something from grandmother's favorite recipes to sweeten the deal. Its amazing how many do want to come early and then have a chance to catch up on all the family news before it gets so busy with activity.
Wonderful site for planning a family reunion. Thanks for all the ideas.
