The Twifect aren't the only ones attending, most of the TwiStars like Gil, Justin, Tinsel, Mike, Boo Boo, Cameron, Kiowa and Daniel will be there....sadly no Kellan or PFach. So far they're only offering premiere packages which are a couple of hundred dollars.
We'll keep you posted as soon as all the tickets go on sale. Don't wait too long i'm sure they'll be going fast! their site has more info.
