Im having a big-ish party (15-20 girls) and we'll get in my hot tub and ill play music and people can dance if they want. I have a creek and gazebo and bridge thing in my backyard, and Ill put snacks in the gazebo. I dont want to plan specific games because that's childish, I want a variety of things to do and people can do what they please. Is there anything else besides the hot tub and music/dancing we could do? Serious answers only please, thanks :)
