I've been planning this party but my birthday hasn't come yet, so I'm going to give this idea to you so you can use it. Okay this birthday party sleep over will work for boys and girls or co-ed. Now I'm doing this party co-ed for my 12th birthday. It might seem to young for a co-ed sleepover but hey I'm responsible. Okay now I'm going to have a birthday party sleep over at the Children's Museum. It costs $500 for a night. You have to have 1 adult to every 10 kids. The children's museum is a good place to have a sleep over for preteens because it is kid like but a sleepover (especially coed) is a way of showing teen hood. You can sleep any where in the Children's Museum. There is a scavenger hunt and a small theater where you can play movies you can bring. This is going to be my favorite party because who can say no to a educational party.
