One of the easiest ways you can save yourself a ton of headache during your next planned party or event is to stop playing caterer. You can spend a ton of money and time buying, preparing, cooking and grilling food for all of your guests, or you can simply tell everyone that it is going to be a potluck party. Hiring a professional caterer saves you a lot of time, but it can be very expensive. When you tell your guests that it is a potluck party, every guest will have to contribute a dish in order to attend the event. This not only saves you time and money, it also greatly reduces clean up after the party, since people will be bringing their leftover food and dishes back home.
Renting out backyard games and boards: cornhole, volleyball, giant Jenga, ladder ball and other games is much easier than attempting a last-minute DIY project or spending a ton of money purchasing games you may only use once or twice a year. There are a plethora of online and local party stores and companies that offer different types of game and cornhole rentals.
Arguably the biggest way to save money at your next outdoor event is to require your guests to bring their own beverages. Perhaps you can make a large pitcher of lemonade or purchase several 2 liters of soda to offer guests when they first arrive. Place all the beverages brought in by your guests on a table, where everyone can have access.
