Some 13 going on 14 birthday party ideas?

Ok so im going to turn 14 on July 24 but i want my party to be on July 2nd... i have a huge list of people on GIRLS of about 15-20 people i was thinking of going to Dave and Busters but it is all the way in Philly so 45min .. too long.. i live near the beach about 10 min away. I want it to be memorable because its going to be on the summer right before i go into the HIGH SCHOOL! any way please help me the sooner the better so i can make invites. THANKS :) :) :) :) :)
