when i turned 11 I had a bowling party, and it was fun. You could do bowling at a local bowling alley, and usually they serve a package of pizza, bowling, balloons, and a cake that you pick out yourself. For only a couple of dollars more you can do glo bowling and its way more exciting and fun and cool . but if you do glo bowling then wear white and you will glow in the dark! u might wanna tell ur guests to wear white too... hope i helped! have fun, good luck, and happy bday!
