there seems to be some confusion about what to do when getting to the will call aka the ticket counter. You have to tell them that you are on the VIP list and give them your name. They will ask for your I.D. so bring one. Drivers License, School I.D., Passport etc will work.
Also please remember that this is a VIP (Very Important Person) party and not a band meet & greet! Although anything can happen at a VIP party.
