I need help! what should I do?

ok so I got invited to a party for the popular kids. you know the kind I ussually dont get invited to. and its somewhat exclusive, but most my friends are going, and it is a party for a guy I used to be really good friends with that I havent seen in over a year! the only thing there is going to be alchol there. nnow im not into that, I probably wouldnt drink any, but should I tell my parents that part? they might still let me go they know I wouldnt do that but still. should I have my parents take me or carpool with a friend? thanks! I am 15 btw
