Be sure you plan a space that’s big enough to fit all of these guests. If it’s an outside party, there may be enough room, but be prepared for a change in the weather. If it’s going to be an inside party, and your home can’t fit that many guests, you can hire a catering hall to host the event, rent a room at the local club, book a room at your golf club, or see if your church has a room you can rent.
