Vegas is my hometown and I’ve been to the strip only a few times, I love it every time I wen’t def. at night, it’s great in that materialistic type of way.
If you don’t go during the holidays, and go in the middle of the week (and if you don’t care about the lights) in the middle of the day you shouldn’t have any traffic problems and even if you do they’re not nearly as bad as in the middle of major cities (like houston or san fransisco at 5pm ugh!)
