Hi, on which web sites can I book bus transportation from Guangzhou to Hong Kong?

I only know the CTS Transportation Development HK Ltd operates the cross-border buses between the Landmark Hotel and HK island, but I am not very clear whether they sell tickets online or not. I usually bought at spot or through some local tour company.

There is no direct buses from the Landmark Hotel to your hotel at North Point. You need to take the bus line Wan Chai area and then use local transportation to your hotel.
