MMP is 30 miles outside of Salt Lake City in Tooele, UT. The Grand America hotel is in downtown Salt Lake. Hop on I-94 to I-80, go all the way through Iowa, Nebraska, Wyoming until you hit Utah. It's basically a one interstate trip all the way from Chicago to Salt Lake. It's boring through Nebraska and Iowa, but on the plus side, the speed limits are all 75+ and the traffic is sparse. The last few hundred miles through Wyoming into SLC is really pretty.
