Transit is something like $3.25 for 2 hours or some such. But there's a free ride zone in downtown Salt Lake, so if you stay in that area (which is where our hotel will be) then you can ride as much as you want :)
Note that we haven't chosen our hotel yet, but we'll be choosing something in...
Btw, the light rail system will travel to the airport and to downtown Salt Lake by the time we have Fall Ball, which means nobody will have to rent a car unless they really want to :joy
