Tips for booking the best hotel deals - What to know before booking

Most hotel companies practice "full disclosure," meaning the consumer will see or be told of all taxes and surcharges on the room rate when the person books through a website or hotel 800 number, Mandelbaum says.
Surcharges to hotel deals could include a "resort fee" at places with resort amenities like a beach, or fees for maid and bellman services when in a city with union contracts with those groups, says Joe McInerney, CEO of the American Hotel & Lodging Association in Washington, D.C. "Some third-party sites may not list all the charges," he says.
Surcharges are difficult to negotiate away, even when you're a member of a hotel's loyalty club, Stone says.
