I had a bowling birthday party. We called to reserve some lanes at the nearest bowling alley. We played a couple rounds. Then went to my house for a Slumber party we had ice cream, pizza, and drank soda. It was really fun! We watched movies and  played board games. In the goodie bags, we put candy, and little bowling pins (so cool!) we had a great time ! The total cost was 500.00 for 27 people. That's not that bad for that many people and it also came with the goodie bags pizza ; food and drinks. Hope you have a great party with this bowling party idea.
