The first question is whether you plan to have a car during your stay. You really don't need one. If you opt to not have a car, you are sort of limited to cab ride distance. But that doesn't mean you'll have to spend megabucks to play. A few closer-in courses that immediately come to mind, that are good value (comparatively speaking):
Angel Park (two courses) - Arnold Palmer design - Currently $75 after 11:00 am weekdays
Legacy - Arthur Hills design - Currently $99 weekdays, $75 twilight
Las Vegas National - Currently $99 weekdays, $75 after 1:00 pm
Desert Pines - Around $75 in the afternoon
Revere (two courses) - Billy Casper design - Currently $84 after 1:00 pm
So there are some lower cost options for very nice courses. I didn't include the goat tracks.
If money is no option, or if you don't mind driving longer distances, there are lots of courses to play. Some are VERY expensive, but others are not too bad.
