Best ticket option for short stay in Hong Kong?

We are arriving at the airport next Wednesday at 07:30, staying at L'hotel Causeway Bay Harbour View 2 nights, and flying out at midday on Friday. I think best option is to buy Octopus card Airport Express Travel Pass to include 2 Airport Express singles to take us to Tin Hau MTR. What is interchange like with MTR? We have luggage. What is exit like at Tin Hau for people with luggage? Overall is this a good option? Please.
