What is TripAdvisor?

TripAdvisor, the world's largest travel site, enables travelers to unleash the full potential of every trip. With over 570 million reviews and opinions covering the world's largest selection of travel listings worldwide -- covering 7.3 million accommodations, airlines, attractions, and restaurants -- TripAdvisor provides travelers with the wisdom of the crowds to help them decide where to stay, how to fly, what to do and where to eat. TripAdvisor also compares prices from more than 200 hotel booking sites so travelers can find the lowest price on the hotel that's right for them. (source)
