I am having my reception at a hall that has beautiful outdoor gardens. I would like people to go out and explore during the cocktail hour, but in the event that it rains, or many of my parents' friends and family who may not want to go outdoors, I was thinking about having some games on the tables to help people get to know each other. Do you have any suggestions? I don't want it to be too cheesey, but I have a lot of family members who are traveling and haven't met other people (some tables have strangers sitting at them because the guests just don't know anyone else who is attending). Thanks.
