How to throw a casual spring break party (teens )
Check with your parents.
Make sure they're okay with you throwing a party, and that they trust you enough to leave you alone. ( who wants parents hovering around the party, sniffing everyone's paper cups? )
Decide when you want to have the party.
A good time is maybe the last day of school before spring break. Have people come to the location at about 6:30 pm (try to arrange it so that they arrive in groups), and let the party continue until around 1 am.
