They're during different weeks so I'll be day tripping to both, sleep at a mates place then drive home in the morning or something. I've been to Surfers schoolies before, it's a bigger atmosphere than Byron, but more dangerous. (Byron goes off in the later weeks though - better than Surfers). Good thing about Surfers schoolies is that Qld'ers finish school at age 17, so the clubs are practically empty haha. If you don't mind a little bit of hippie culture, you're going to love Byron schoolies.
