Turn Left on 1st Street. Golden Nugget will be on the right, self parking on the left.
Following signs to downtown takes you through the big I-15/I-95 interchange, known as the spaghetti bowl, which can have brutal traffic on a Friday afternoon/evening, plus it overshoots your destination since the Golden Nugget is on the South Side of Fremont st, which of course doesn't actually allow car traffic anymore in the downtown area.
