How much four persons 7 days stay will cost. Can u suggest some good accommodation?

1. First of all, there is no direct flight. You are advised to take a plane to Beijing Capital Airport first. Then transfer the flight to the destination. In usual time, the whole fare is CNY 4,500 to 5,000 per person.
Or arriving at Beijing Airport, you can also take shuttle line 10 to get to South Railway Station. Then take the direct bullet train. The ticket fare of second class seat is CNY541.5 and first class seat is CNY834. You can choose the way you like.
2. About the accommodation, you can stay nearby Central Street. There are many shopping malls and nice restaurants. And the surrounding transportation is convenient. Yitel Hotel (Central Street Branch) is a good choice. The price for a hotel room with two beds is around CNY 400 per night.
3. Generally speaking, it will cost CNY 3,000 to 3,500 per person, not including the airline tickets.
