A pool party is the perfect way to celebrate any summer event, from a birthday to the Fourth of July. But before you can dive into the fun, there’s a lot of planning that goes into making sure your pool party is a success. Choosing a theme for your pool party will make the planning process much easier. Once you have a theme in mind, you can start planning decorations, food, and activities that all fit within that theme. Some popular pool party themes include Hawaiian, beach, or pool Olympics.
