If i were you, since your 18, buy alcohol and have some friends round, have lots of fun. Obviously apply a little bit of common sense and don't have an entire army of randomers turning up on your doorstep, but with a dozen or so friends you could have a pretty cool party.
Also, have sleepovers, and stay up as late as you like and watch films and play music.
Be imaginative!
Edit: scrap that, apparantly your a Brit in New York- just do the sleepover, unless you happen to be friends with a 21 year old.
