This is part of the Las Vegas strip, where many of the hotels are. The strip is the new Vegas, as I was told by a shop attendant. She said old Vegas is more "honky tonk" (okay, I don't really know what that means .....) with a lot of cheap motels. Tourists don't visit old Vegas much.
I didn't visit the hotel in the distance - the Wynn - but it had the most gorgeous lighting arrangement on its grounds, which came on at night.
