How can I travel from Hong Kong Airport to Hotel Prudential,Jordan MTR?

1. To your hotel by public tranbsportation, here are two ways:
Take airport express to Kowloon station and transfer to free bus line K1. Get off at the 1st stop - Jordan Station (Austin Road) and walk to your hotel. Or directly take shuttle bus line A21 and get off at Prudential Centre, Nathan Road. Then you will spot your hotel nearby.
P.S. as you are traveling with the seniors and kid, you may consider booking the pick-up service from your hotel.

2. For your 8 days' stay, I suggest you buy the Standard Octopus Card. The seniors and kids shall enjoy some discounts.

Dear Juana,

Thank you very much for your very practical advice. Based on what you have said I intend to:
1) Take Bus A21 direct to Prudential Centre from where the Hotel entrance should br close and easily acessible, and
2) I will get Standard Octopus Cards for the Adults, Elder Octopus Card for those 65+ and a Child Octopus Card for our 7 year old.

Thank you, much obliged,

Basu
