Bora Bora was the most expensive city for U.S. travelers with a daily average of $770 a night followed by Soufriere in St. Lucia with $464 a night. Meanwhile, Wailea in Maui was the most expensive U.S. with daily averages rates of $437, followed by the Newport Coast of Calif. ("The OC B*tch!") with $427 a night. The rest of the list is dominated by Caribbean and California destinations with Monte Carlo being the only European city at $353 a night.
Popular destinations for U.S. hotel guests remained the almighty trinity of Las Vegas, New York and Orlando but it's in San Francisco and New York where guests will pay the most for a luxury hotel, followed by Paris. If you want a posh hotel in San Fran, you can expect to cough up a mind-boggling $562 a night. (NYC was $550)
Given that some might think San Fran is the new NYC (warts and all) then this isn't really that surprising after all.
