We want to take a van-taxi from beijing Airport to our hotel in the centre.

Hi, a normal cab can accommodation at most 4 passengers and 3-4 pieces of large lugagges. And the cab fare to the downtown is CNY100 or around.

If you have a lot of luggage, you can enjoy pick-up service. I know Travel China Guide has this service. You can book the van in advance. They will send you to the hotel directly. It brings you a lot of convenience. If you want, the contact information is bookingtravelchinaguide.com.
