Las Vegas, not Honolulu, is the most expensive city for hotel room service in the U.S., according to research by TripAdvisor.com.

Honolulu ranks at fifth-most expensive.

The 2014 TripIndex Room Service study did a cost comparison of common items and services many travelers will experience, such as the cost of in-room amenities in 62 popular cities around the world, including 15 in the U.S. The study showed no correlation between expensive hotel rooms and pricey room service in the U.S., but both attributes were commonly found together internationally.

The comparison includes the price of a club sandwich ordered through room service, the dry cleaning of one shirt, and mini bar items including a bottle of water, peanuts, a mini-bottle of vodka, and a can of soda.

Las Vegas’ total room service cost of $68.01 was ahead of $67.83 in second-ranked New York City, No. 3 Wash., D.C., at $61.66, No. 4 Los Angeles at $60.67, and Honolulu at No. 5, with a total room service cost of $60.67, though it should be noted that some Waikiki hotels have discontinued room service operations.

Of the 15 measured, the three markets with the cheapest room service in the U.S. are Denver, Colo., at $41.43, Seattle, Wash., at $41.58, and Minneapolis, Minn., at $45.72.
