It'll be too crowded, the weather will be too hot or too wet, there will be rubbish everywhere, the music will be too loud or not loud enough, and you'll probably get stuck by the shittest sound system because that's where all your mates are, missing the good stuff on the other side of St Pauls. You'll wait ages for your mates to find you, only for them to turn up just as you were about to leave. Just when you do find somewhere good to hang out, you'll find out your mates are either on the other side of the carnival or they'll have got too hot, too pissed, too fucked on pills, or just got too bored and gone down the pub. It'll be the best thing you've ever gone to or the most overrated. It will be the best/worst it's been since X years ago, and you'll probably have either the most banging night out or the shittest night out of your entire year.
