Hong Kong Airport Express Travel Pass please

I intend to buy the Airport Express pass at HK 220 with one time journey from my hotel at Mirador Mansion to go back to the airport with the 3 days unlimited MTR ride. Is this possible with the 220 card?

When I am at the airport upon arriving at 1pm, I intend to take a free shuttle bus from airport to my hotel at Mirador Mansion and how to go about it? Where to board this free shuttle and where shall I stop to go to my hotel and do I have to show anything like boarding pass to get on the free shuttle and how long is the journey? Thank you.

So I still have a journey ride on the Airport Express MRT correct with the HK 220 pass?
