there are plenty of nice places and areas that are 12-15 minutes for unlv on the west side of the 15... even on the east side if you go south slightly, probably better traffic patterns also. certainly better than trop and jones
Anywhere along the 215 corridor(west and east of the 15) is within that 15 minute window for sure... the further west you go the nicer the area, but I might stay south of Durango for times sake. I can get to the MGM in about 11-12 minutes and I am off Buffalo and the 215
