    For Wilson, the two most important things to take with him when he travels abroad are his passport and his mobile phone. He books his plane tickets and hotel rooms through the Internet, and he enters all the information into his mobile phone. "I don't even need to print my tickets out any more," says Wilson. “I can do everything online.”

How people travel and go on a holiday has changed a lot over the past years. Airlines, hotels, travel agencies all have their own websites. People can plan and book their holidays just in some clicks. Today everything is easier, faster and smarter.

In fact, many people do not use guidebooks any more. Instead, they go to travel websites for the maps and information. These websites also let travellers write about and show photos of the sights, hotels, shops and restaurants they have been to. This means other people can read about their experiences and decide whether they want to visit these places too. The Internet has made it easier for everyone to share their experiences and thoughts with each other.
