I live in Vegas... There is usually 250-350K people on the strip for the fireworks. This years show should run about 45 minutes due to the 100 anniversary of Las Vegas. The best place to view the show is from you room if you are staying on the south end of the strip, if not on that end any place is good. They close the strip from Sahara to Trop down starting at about 9PM for vehicles, you have to walk the strip. 2 years ago we were down there, it took 3 hours to get to the car and leave the strip after the show, we will never do that again. We live on the NW side of town, about 15 miles from the strip and watch it all from the balcony at the house.
