Do you have enough tables and chairs for the family reunion? What about propane grills for cooking?
Depending on how many people you expect to attend and where you will hold the reunion, you may need to arrange more furnishings. If you're holding it at a hotel or vacation destination, they should take care of furnishings for you. But if you're holding it in a home or at a local park, you'll need to take care of furnishings yourself. Here are some ways to do it.
Regardless of how you get the furnishings, it's a good idea to reserve or purchase them early to make sure you'll have them. It will be one less thing to worry about as you get close to the date of the reunion.
