Outta-School Party!

Hey everyone!
Im 13 and me and my friend are planning an outta-school party w/ about 40-50 ppl from 5-12:30 at my house. So far were gonna have a volleyball net set up, basketball court, and a place to play football. We`ll also have my pool if we open it and if we dont open it then were gonna have a water balloon fight. Were gonna have a bonfire later and were gonna play jail break (sorta like hide n seek)
We duno if we need more stuff to do or if u think thats enough we dont wonna really plan it but just have things to do while were hanging out
