How to plan my huge party?

I am 16 and throwin a huge party, how do I make my party, btw it's friday and I have 4 days to really plan it

hmm... maybe ask and see if you can rent the jym in yer school...thats what I did and it was an amazing party..but yer going to need some money to rent it to buy food and if you want to dance party with music you need to hire a dj and you will need money fer that 2. so ya theres an idea..big danceee partaaa

Get lots of yummy food and lots of great movies and good music!
