hi...i'll be going to shenzhen next month and will stay at kempinski hotel.

No shuttle bus can reach your hotel directly. You can take a shuttle bus from the airport to Hourui subway station to take Luobao Line to the Window of the World, and then transfer to Shekou Line to Houhai, get off from exit D2. Walk to the west to your hotel. For the return ride, you can do the same way.
