Here's how I go:
Swenson to Harmon which is just past Tropicana.
When you reach Harmon you can then get into one of the 2 left-hand lanes and after turning
you go one short block and turn right on Paradise to LVH.
Another way, instead of turning left on Harmon, turn right on Harmon and go one block to Joe Brown
and turn left. Go straight down Joe Brown to LVH and their parking garage on the left.
I prefer Joe Brown because there's usually less traffic and so far no construction problems.
Either way, it's about 10 minutes or less.
