Shenzhen airport to Kowloon
 

I'll be in Shenzhen on business this month and after leaving my colleagues at the Shenzhen airport I'm spending a week in Hong Kong. What's the easiest (not necessarily the cheapest) way from Shenzhen airport to Kowloon and back? I'd prefer to take a ferry if possible but what are my options?

Easiest is private limo - you don't need to get out of the car at the border. Second is the "direct" coach to the Elements Mall in West Kowloon.
