The leading mobile nightlife guest list aggregation and direct response application today announced the addition of four Las Vegas nightlife venues to its service. Guest List Nation announced the following nightlife venues are now utilizing the mobile event marketing service: Ghostbar, Moon, Playboy Club and Rain; launching Las Vegas alongside the current markets of San Francisco, New York City, Chicago, San Diego and Phoenix/Scottsdale.

Guest List Nation CEO, Trevor Hewitt, stated “the addition of Las Vegas is a major milestone for Guest List Nation as our users have been asking for authentic guest list offers while visiting Vegas. When we launched Guest List Nation, we believed venues were looking for an alternative and cutting-edge way to market their businesses; adding Las Vegas to the service really validates our position in this emerging market.”

Guest List Nation launched the iPhone version of the application on March 4th, 2010 and within three months has opened its sixth market and is now powering the mobile marketing strategy of 70 nightlife venues nationwide with plans to launch Android and BlackBerry versions on July 15th. Guest List Nation service is also available via its own stand-alone website.
