I did a flight from North Las Vegas with West Air. The instructor was not up to much I have to say and spent very little time with me briefing on the area. On reflection I should have devoted a whole day rather than a few hours. The flight was spectacular and McCarron were quite happy to vector us right over the threshold of the main runway there.
One word of warning: many of the taxi drivers don't seem to know their way to anywhere outside the main tourist destinations; also make sure you arrange transport back to the centre. It took me over an hour to get someone to pick me up - the courtesy bus the flight school told me operated from North Las Vegas to the strip had stopped!
