An interesting question given the specific, unconventional (and somehow unfortunate) choice of hotels.
Nowadays, Macau hotels usually provide complimentary shuttle bus service to customers. Inn Hotel seems to be no exception, but after a closer look... (emphasis mine)
To welcome guests from the first moment they arrive, we provide a complementary shuttle bus service to and from the Grand Emperor Hotel and Macau Ferry Terminal & Rorta Do Cerco.
What's the hotel name again? I think you'd better ask the hotel about the exact details of the shuttle bus.
From Macau to Hong Kong there are three Macau ports, sorted from nearest to farthest from hotel: Taipa Ferry Terminal, Outer Harbour Ferry Terminal, and Hong KongβZhuhaiβMacau Bridge Macau Port. Please ask if the hotel provide shuttle bus to which of these ports. When you have luggage, using hotel shuttle bus is always better than taking public transport in Macau. If the hotel really fails you, take TransMac 26 from Jardim Cidade das Flores to Taipa Ferry, or TCM 28A from Treasure Garden to Outer Harbour, or Transmac 102X from Treasure Garden to HZMB Macau port.
If you take the ferry from Taipa or Outer Harbour, always pick Macau Ferry Pier (in Sheung Wan, Hong Kong Island) as your destination, instead of China Ferry Terminal (in Tsim Sha Tsui, Kowloon). It is because (1) there are more ferries going to Macau Ferry than to China Ferry, and (2) Macau Ferry is closer to your destination. After the ferry trip, take CityBus 37B (Macau Ferry -> Tin Wan St) or CityBus 71 (Macau Ferry -> Hing Wo St).
If you use HZMB, you will, in HZMB Macau port, buy a ticket for a bus ride ("Golden Bus") to HZMB Hong Kong port. There, you need to take two buses: Citybus A11/A21/A22/A29 to Lantau Link Toll Plaza, then CityBus A10 to alight at Tin Wan St. To enjoy a much cheaper bus fare, pay by Octopus card for interchange discount.
So you have three main options, each with minor variants:
Take hotel shuttle or TransMac 26 to Taipa Ferry; take Cotai Jet ferry to Macau Ferry; take CityBus 37B/71 to your destination.
Take hotel shuttle or TCM 28A to Outer Harbour Ferry; take TurboJet ferry to Macau Ferry; take CityBus 37B/71 to your destination.
Take hotel shuttle or Transmac 102X to HZMB Macau port; take "Golden Bus" to HZMB Hong Kong port; take Citybus A11/A21/A22/A29 to Lantau Link Toll Plaza; take Citybus A10 to your destination.
