World's top 20 business hotels (Photos)

Hotels that combine service, technology and comfort have topped a list of the world's best business hotels with the winners offering their guests those added extras that can make all the difference to a trip.

Readers of travel magazine Travel + Leisure ranked hotels on a list of services and amenities to come up with their 20 top business hotels, part of the publication's annual World's Best survey.

Some offered free Internet access and a 24-hour business center, some had rooftop pools, while one had an award-winning Gordon Ramsay restaurant. Free parking was also a plus.

Boston's The Eliot had touch-screen monitors for guests to order room service and print boarding passes. The Peninsula Hong Kong transported one guest in a Rolls Royce and treated her to tea upon arrival.
