Do you think it would be a good idea to have a party?

Okay well my 15th birthday is June 17th and I was thinking about having a party it would probably start at 7 p.m and end whenever. I have a pretty big yard, trampoline, ping pong table, foosball table, kan jam, and a fire pit. The only thing is I've never thrown a party before and i'm not sure how to keep it going and stuff and if it will be good at it or not. I am a pretty popular kid and everyone knows me (not trying to brag or be self centered.) But I am I freshman and I hang with mostly freshman and junior kids. So I would probably invite 60 people and hopefully like 35 will show up. But do you think it's a good idea? Any party advice?
