Hi, we're visiting Macau this July 30 from hongkong.

Hi Freya. You can take a ferry from HK to the Maritime Ferry Terminal. Then take the free shuttle bus of Hotel Sintra to the hotel. Then walk for 3-5min to the Senado Square.

To Venetian, you can still walk to Hotel Sintra and take the free bus of City of Dreams to the terminal. Then the Venetian is right at the opposite.
