Saved a lot of money and time by being at a hotel off the north monorail, which offered a quick easy way to get in and out.  Smooth and driverless, frequent trains until late hours, clean and not even too rowdy on New Years.  Unfortunately very commercialized with annoying voiceovers that repeat over and over, and you have to walk through the \"gift shop (casinos) in order to get out.  Plus the stops are dang hard to find as they are not well marked in the casinos and sometimes the entrance is a few hundred feet away from the platform without an ability to get in without backtracking through the casino on pedestrian-unfriendly driveways.
