Thanks to the crowds, Las Vegas is as safe as any other big city for a woman traveling alone. A woman on her own should, of course, take the usual precautions and should be wary of hustlers and drunken businessmen who may mistake her for a "working girl." (Alas, million-dollar proposals à la Robert Redford are a rarity.) Many of the big hotels have security guards stationed at the elevators at night to prevent anyone other than guests from going up to the room floors. If you're anxious, ask a security guard to escort you to your room. Always double lock your door and deadbolt it to prevent intruders from entering.
