Once travel season begins , every city is full of promotion al advertisements for  travel offices. Some professional person s remind travel lovers to look out for travel advertisement.
　　
　　Flight　 Travel agenc ie s will list flights' size in the advertisements ， but they won't list the time 。 Generally ， the tickets for an i nconven i ent time are cheap. If agenc ie s buy all seats in a flight, the price will much cheaper than normal tickets. Some travel agenc ie s arrange flight s at night in order to save money,which cause s tourists to feel tired and have little interest in the tour the following day.
　　
　　Accommodation　 ravel agenc ie s' advertisement will list the level of hotel. At same star level, the price difference was caused by the hotel's location. If the hotel is n ot in a scen ic area or far way from a scenic area, the price is lower, but the consumers must back and forth from scen ic area and hotel , which cost a lot of time and energy
　　
　　Food & Beverage　 Travel ads list how many meals are provided; some even provide the price of the meal 。 But whether the quality of the food equals its price is a completely different issue. There may be a trick 。
　　
　　Tour bus　 Tourists mainly take tour buses after arriving at their travel destination 。 Some buses are in good condition ; some are not. I.e. some buses have insurance, while some do not 。
　　
　　Tickets　 Several travel agents announced that their travel fees include tickets. However, there is a distinction among tourist attractions: “big tickets” and “small tickets” . ＂ Big tickets” only permit entrance to the gate of the attraction. ＂ Attractions inside attractions,” “ gardens inside gardens” all require extra fees .
　　
　　Attractions　 Several travel agents provide a long list of attractions, which give an impression of a “ rich” trip. However, these lists may be corrupt. One attraction may have several names, or several attractions may have a cheap ticket or be free 。 When you pay, check carefully. Do not look at the price only and ignore the content 。
　　
　　shopping　 the total number of travel days are the same, but the travel agent can arrange many shopping activities. The tour guide doesn't force tourists to go shopping , but it costs much precious time, and shortens sightseeing activities 。 Tourists' cost are not small .
