Bus to The Lagham Hong Kong

I will be staying at The Langham, which is located at 8 Peking Road, Tsimshatsui, Kowloon. I will have the HK Airport Express Travel Pass for 3 days. I was thinking of taking the express train to Kowloon. Since the Free Shuttle Bus does not go directly to my hotel, I was thinking of taking the Shuttle Bus (K2) to Marco Polo Hotel and than walking to The Lagham. Whill they let me onto the bus to do this or do I have to show that I am staying at Marco Polo Hotel?
