Whats the best kind of alcohol to take to a music festival?

Since i'm underage when i'm going to leeds fest i won't be able to buy alcohol there, so i'm going to have to take all the booze that ill need with me. therefore i need something thats gonna get me pretty drunk off quite a small amount since i dont want to be carrying loads of booze. I've considred vodka, but i can't really stomach it anymore, so does anyone else have any suggestions, like a box of wine or malibu or something like that?
