     You can love them or hate them, but no matter which tourist destination you visit, chances are you'll

see someone with their head buried in a Lonely Planet guidebook.

     Lonely Planet is one of the world's largest travel guide brands, publishing more than 500 different

guides in eight languages. The popular brand also produces television shows, websites and podcasts (播客)

all devoted to travel.

     Some people praise Lonely Planet books because they make traveling easy and affordable. They also save

time and make sure you don't miss the best things.

     They also provide the reviews of hostels (旅店), hotels, restaurants and ticket information about your

destination.

     This can be great if you're a nervous traveler, or if you haven't traveled hy yourself before. If you're in

a country where you don't speak the language, sometimes there's nothing better than getting into a taxi and

opening up a guidebook. You simply point to a map that directs the taxi driver to a hostel that's cheap and

clean, with friendly staff and cold beer.

     But others criticize Lonely Planet and other travel guide publishers like them. They say guidebooks take

the fun and spontaneity (自发性) out of traveling, and that part of the enjoyment of travel comes from the

fact that anything can happen. They also regret that if you follow a guidebook, you'll end up doing the same

thing and having the same experience as everyone else. You might end up seeing the same group of people

over and over, because everyone is reading the same book and following the same route.

     Another criticism of travel guides is that they have a large impact on local communities. For cxample,

some locals devote their lives to behaving in ways that attract tourists. They pretend to live a traditional

lifestyle, wear traditional clothes and live in traditional houses in order to attract the tourist dollar.
