Where are some cool places I can have my party if I don’t want to do it at a house or rented hall?

If you want to do something different for your sweet 16, then you should definitely consider throwing your party somewhere fun and unique such as a spa or an amusement park. Some other fun locations include: a park or baseball field, an art studio, the beach, a rock climbing studio, an arcade, a nice restaurant, or outdoors at a camping ground.
