If you’re interested in booking a hotel this New Year’s Eve, get ready to pay up.

Hotel rates in Los Angeles are going to the penthouse level this Dec. 31, according to a survey by LosAngelesHotels.org.

Hotels with vacancies remaining are charging nearly 150 percent more than their average rates and some much more than that, according to Daniel Berger, a LosAngelesHotels.org spokesman.

“It’s getting more and more expensive on New Year’s Eve, in particular in downtown L.A.,” Berger said. “Three years ago, the least expensive three-star hotel room did cost $200. This year, you will have to spend $400.”

A room with a queen-sized bed at the Best Western Hollywood Hills normally costs $136 a night, but that price is being hiked to $626 this New Year’s Eve, the survey says.

The Ace Hotel Downtown L.A. is charging $676 for a room with a king-sized bed compared to its normal rate of $251 a night, according to LosAngelesHotels.org.

However, Pasadena has some of the highest increases with the Pasadena Rose Inn, for example, costing $690 the night of Dec. 31 for a room with twin beds compared with its regular rate of $102.
