Try touring the Shanghai World Expo Site at night if you are tired of the endless queues, the blazing
sun and crowds of people during the daytime. Nitht -time tickets for the Shanghai World Expo are already available, and tourists can enjoy a completely different view when night falls.
First, night -time tickets are much cheaper and tourists can avoid peak hours. A daytime ticket costs
160 yuan, while a night-time ticket only costs 90 yuan.
Second , night-time tickets save tourists a significant amount of time spent in queues so they can visit
more pavilions. On the whole, although going at night allows only half the time during the day, tourists
spend less time in queues and can visit roughly as many pavilions as in the daytime.
Third, the lights are all on at night, giving tourists a wonderful night view of bright lights that they cannot possibly see in the daytime. Dressed with all kinds of colored lights, the Expo Site looks brilliant and
charming at night.
Fourth, the Expo is more
pleasing and comfortable at night because pavilions provide more and better interactive activities at night. There are performances at the Expo Cultural Center every night, and concerts performed by world-famous singers on weekends.
Fifth, services are still excellent at night. Tourists can glut themselves with delicacies at a food plaza (广场) which is ablaze with lights even past 10 p.m.. In addition, the plaza is much less crowded and busy at night than during day.
