Travellers can book rooms on a computer by using online security to protect their privacy and financial information and by using several online travel agents to compare prices and facilities at different hotels.
Online hotel reservations are also helpful for making last minute travel arrangements.
Large hotel chains typically have direct connections to the airline national distribution systems (GDS) (Sabre, Galileo, Amadeus, and Worldspan).
These in turn provide hotel information directly to the hundreds of thousands of travel agents that align themselves with one of these systems.
