I paid two dollars at the City Creek Mall garage when I went to a concert recently. The first 2 hours were free.
You can call Raddison and ask how much it is for their parking garage. Some parking lots will have signs up with prices posted. I live in Sandy and when I have time I just take the train (if I don't use Raddison) in and it stops right in front. Good luck.
Best and timelyness would be the City Creek parking, the Nordstrom end. Cheapest would be any of the free street parking in the area if any are available.
