Airport Hotel transpportation to The Langham Hotel in Kowloon, Hong Kong

My husband and I arrive late at night so opted to stay at an airport hotel and travel in to the city next morning. Iunderstand that the airport express is the best method but from where it stops in Kowloon how far to the Langham is it to walk with 2 suitcases?
Our adult children arrive the next evening late at night so this information will help all of us if any one is familiar with The Langham

Thanks in advance
