yeah i was 17 at schoolies
all we did at night was stay in and watch movies, go in the hotel's hot tub or pool, went out to dinner a couple of times and then went to this pier (in nelson bay) and hung out there.
our hotel was too far from a beach to just walk down there at night- i think the closest beach was a 10 minute drive. would've loved to have a bonfire or something though. ah well.
