One daughter was not a fan of this kind of stuff and would only go with friends (finding a buddy excellent idea for the less adventurous). For DD1 she needed this to open her up to experiences.
My other daughter liked going to this stuff, made tons of friends and lots of new Instagram followers (which I think is important?) Only issue was hearing about all the food stations she could pick from...no we don’t have a pizza, ice cream, salad, or sandwich station at home. I heard more about the food and swimming pool than softball.
