Honolulu has leapt to the top spot on an annual TripAdvisor list, but the news could give potential visitors pause about booking travel here.

The travel site ranks Honolulu the highest-priced U.S. destination this summer following a 29 percent increase in summer hotel prices since last year.

Honolulu jumped four spots from the summer 2012 list, “leapfrogging” New York City, Boston, and San Francisco, according to a statement.

The site’s TripIndex Cities list bases its rankings on the combined costs for two for a one-night stay at a four-star hotel, cocktails, a two-course dinner paired with a bottle of wine and round-trip taxi transportation of two miles each way.

Honolulu costs rang up at $504.94 compared to No. 2 New York City at $504.25 and No. 3 Boston, at $473.59.

The same night in Las Vegas, the cheapest U.S. city, would be $272.94.

Oslo, Norway, tops the list of international destinations at $581.08. Oslo is followed by Zurich, Switzerland, at $523.41, and Stockholm, Sweden, at $521.68.

The least expensive international destinations are Sofia, Bulgaria, where the same night would cost $158.42, followed by Hanoi, Vietnam at $176.14, and Warsaw, Poland, at $187.45.
