I don't know about the corporate dollars.
Nevada has two companies in the Fortune 500 (both are casino/resorts). Neither is in the top 200.
You are talking about a travel destination city and a plastic one at that. Every company in the area will have plenty of season tickets for them to give away. Sure, it will be a less 'die hard fan' crowd but tickets will be sold. It will look much like a Super Bowl crowd. Corporate tickets everywhere.
