Just Out Of Curiousity...

I didn't walk around the entire place, but no I don't believe there are. If you have a gold badge, there were some in the VIP lounge area.
 
well if the pre party was held at the Riveria (PP 2,3,4) then you could have nice seats up on the back level. Plenty of room to mingle with band members ex. Its just not the same at vinals...upstars or down.
