TripAdvisor has examined millions of travelers' reviews posted on its website to come up with the top U.S. and worldwide destinations for this year.
And the winners are: New York City for top U.S. destination and Istanbul for top worldwide destination.
The sixth annual Traveler's Choice Destination awards honored nearly 500 locales across all continents. TripAdvisor weighs users' rankings for hotels, attractions, and restaurants at the destinations over a 12 month-period as well as the number of times the city is pinned as a favorite.
New York City was the top U.S. destination for the fourth year in a row. It was followed by Chicago, San Francisco, and Las Vegas. New Orleans moved up the rankings five spots from last year to claim the No. 5 spot.
