Nearly 10 years ago Las Vegas made the iconic assurance that “What Happens Here, Stays Here.” But now, the age of instantaneous information sharing through constant Tweeting, texting and revealing Facebook status updates are threatening Las Vegas’ defining code. And the destination is fighting back.

Las Vegas is leading the charge against information over-sharing with a chic, new, PSA-style campaign urging its more than 37 million annual visitors to protect their Las Vegas moments and the destination’s discreet adult playground reputation by remembering the “Only Vegas” code. Tapping into the very social media avenues it is attempting to lasso, the destination will virally launch ads encouraging travelers to withhold those experiences meant to stay only in the destination and to take an oath promising to do so.

‘“What Happens in Vegas, Stays in Vegas” is not just a catchy slogan for the destination,” said Cathy Tull, senior vice president of marketing for the Las Vegas Convention and Visitors Authority. “We are a world-class destination not only defined by our fine dining, shopping, mesmerizing entertainment and luxury, but also by our incomparable reputation of providing and protecting an atmosphere of adult freedom.”

The “Entertainment Capital of the World” offers visitors a uniquely fun atmosphere to indulge their unexpressed selves and play boldly. And to protect this reputation, Las Vegas is reminding its visitors to practice “safe text,” and to ask themselves before posting photos or updating status updates on social networking sites, “Is this what they mean by ‘What Happens Here, Stays Here?’”

So what are visitors encouraged to share publicly?

For instance, travelers may Tweet about rocking out to the many talented DJs electrifying Las Vegas’ nightlife. Perhaps send a Facebook update about enjoying a delicious meal at the countless world-class dining options at the Strip resorts. Or text Mom & Dad about being blown away by any of the destination’s incredibly performed and produced Cirque Du Soleil shows.

Travelers who feel they broke the “Only Vegas” code during recent visits to the destination or who simply want to join the campaign to protect the uniquely Las Vegas experiences are urged to visit www.VisitLasVegas.com/knowthecode. Here they can sign the oath to protect the moments and spread the word to their friends about this social lifesaver.
