is there any van transport (10 pax with luggages) from Sunon Hotel to Shenzhen Airport, cost?

You can ask your hotel to arrange the van service for you, the fare would be CNY250 – 300.
Or you can walk to nearby Laojie Station, where you can take the subway Luobao Line to Hourui Station (CNY8 per pax). Then take the airport connecting bus from the station to the airport (CNY2 per pax).
