Primm Valley Resort & Casino, located on the border of Nevada and Southern California, has completed a $7 million renovation, according to Fox 5 Vegas. Western-themed guestrooms feature modern touches, including light sensors to cut down on energy costs. Other upgrades include new carpeting for the casino floor and a Denny’s restaurant. Buffalo Bill’s Resort & Casino, which has the same owner as Primm Valley, underwent a rejuvenation in fall 2010.
