ahhh... what are your immediate concerns?
I'm not really sure why there are so so many questions about it, but travel from LAS to any of the Las Vegas Strip (or slightly off strip locations) has truly got to be one of the easiest airport to hotel trips in the entire world.
Yeah, there is the occasional "tunnel" issue, but even a long haul in Vegas to the strip is only going to cost one $5 to $10 extra. (It's not like a long haul say, from JFK to New Jersey, or even Manhattan)
So, don't worry so much about getting to your hotel, it's going to be fine (believe me

) instead, spend the time worrying about how you are going to extract $$$$$ out of the casinos.
