Bear in mind that what is legally the city of Las Vegas and what people
informally call "Las Vegas" are two different things; most of the Strip is
in unincorporated Clark County, not the city of Las Vegas proper.  See eg

Defining an alt_name or loc_name of "Las Vegas" on each of the surrounding
CDP boundaries/relations may help Nominatim geocode these cases better.
 But the CDPs are not part of the city (aside from any areas that may have
been annexed, which should be reflected in the new TIGER 2013 boundaries)
and should not be conflated with the city boundary.
