Hey, I just booked a last minute vegas trip(2nd in 3 months from Boston) I'm going sept 20th, the weekend of the iheart music festival. Has anyone ever been to the previous ones? Before I hit the online secondary market, I was wondering if anybody knew what it's like for tickets at MGM before the show or any big event? Lot of scalpers? Is it legal to scalp tix in Vegas? Are prices significantly less at show time? I don't mind getting in late...thanks for any info!!
