Well, that's what he said. It's DT - he could go longer. But, he started at 6pm so I doubt he'd go more than 24 hours. You're best bet would be to text message someone in there to see if the party is still going on.
I went to the party last night - it was $30 at the door. Good crowd, packed but not too crowded. When I was there Danny announced he'd be going till 6pm tonight.
