I have booked my hotel at Kowloon, i want to reach Hong Kong convention center at 7:45 Am on Monday.

Well, Kowloon covers a large area. Do you refer to Kowloon Station? If yes, take MTR Tung Chung Line from Kowloon to HK Station. Then, take MTR Island Line from Central Station to Wan Chai Station, Exit A1, and walk north to it. The fare totals HKD 9.7, and the trip takes about 25 minutes. :)

Hi. Thanks for the reply. But I need to reach hk convention center at 7.45 am, so is it possible to catch train so early? I'm worried i should not be late at presentation.. kindly reply.

The first train departs at 06:01. So you can certainly reach the center by 7:45. Don't worry! :)
