World travel has moved on to a new level as new websites appear to enable travelers to plan their trips online． Virtual（虚拟的）tourism is the latest name of the game and although relatively new， has seen some tourism websites grow to host over one million users．
Typically， this development features a website that contains the answers to almost any tourism question． Tips and information are not provided by a single source， such as the website host， but rather from travelers themselves---often in the thousands． This has proven to be exceptionally beneficial for would-be travelers who are seeking information on questions such as where to find the best museum or beach， whether it is better to tour Brussels with a bicycle or on foot， and which exchange rate bureaus are available in Italy． Questions about food and restaurants， tourist spots， safety， accommodation， and others are all answered． In addition， posted tips promote better preparation， such as what to pack when heading for Sicily．
Apart from the useful tips， visualimages and virtual tours have also been made available． If you'd like to visit the Eiffel Tower， it's a good idea to view the surrounding areas， to pick a safer train route， or to know that it's very close to the Seine River and that a walk along it would enhance the experience．
Virtual tours have sprung up globally． In South Africa， John Gore established the Virtual Tour Guide in November last year． On his blog， Gore was quoted as saying， "The world is panoramic（全景的）．"
"We are able to turn our heads and look in all directions and get a feel for where we are， but the typical photograph cannot show or describe that experience completely．"
However， there is an answer一technology makes it possible to share the world around us in a 360 degree panoramic way， which really makes the viewer feel as though he or she is really there．
