People can chime in on the DJ and whatever, but IMO having been to a lot of other stadiums, the gameday experience at Hardrock is pretty good. The roof and renovations done however many years ago it was now were game changers.
It’s actually one of the easiest stadiums to get in and out of too, pike/595/95 traffic notwithstanding.
I think they can try more gimmicks (whatever night, bla bla bla), and toy with the ticket prices to hit the sweet spot, but the bigger factors come down to the success of the team and general promotional efforts.
