Puerto Vallarta, Mexico - As one of Mexico's most attractive destinations, Puerto Vallarta's steady growth has been accompanied by improved services, an extensive expansion of its infrastructure, and an increasing number of cultural activities to better serve both the growing number of travelers who visit the destination every year, and the city's ever-growing population.

And now, travelers who have recently visited have the opportunity to help Puerto Vallarta win the designation of "Best City" in Condé Nast Traveler's Readers' Choice Awards, one of the tourism industry's most prestigious awards - by participating in the annual survey.

Condé Nast Traveler is a luxury and lifestyle travel magazine published by Condé Nast. The magazine has won 25 National Magazine Awards. More than 300,000 travelers take part in the Readers' Choice survey, submitting millions of ratings and more than 100,000 comments to create a list of winning favorites on an annual basis.

The coveted Readers' Choice Award is a seal of approval for the travel industry from the world's most discriminating travelers - that's you! - so please take a moment to take the survey at cntraveler.com and help Puerto Vallarta secure its well-deserved place at the top of Condé Nast's 2018 list of the world's best cities.

There are many other categories in the survey, so vote for as many listings as you like. Full results will be published online in late October and in print in the magazine's November issue. The best of the bunch will be featured online throughout the year.

Another great reason to vote? You could win a trip for two to Europe! Every time you submit a survey, you will automatically be entered into this year's sweepstakes.

The grand prize is a 15-day, 14-night Viking Homelands Cruise with Viking Ocean Cruises from Stockholm, Sweden to Bergen, Norway, including round-trip airfare from the U.S. The cruise, on board one of Viking's newest ocean-going ships, includes stops in St. Petersburg, Russia; Tallinn, Estonia; a land detour to Berlin; and a visit to Copenhagen.
