Paradiso and ID check?

How thorough is USC with checking IDs at a big event like this? I myself will have no problem getting in since I'm 18 but some of the people I'm going with don't turn 18 till July and another is 16. They plan on borrowing other peoples IDs that look like them so they're legit IDs. The girl that is 16 was successful in getting into Lucky using this method, but Paradiso is a totally different ball game.

Thanks!
