hi! Can i know whats the easiest way to get from Venetian to Senado Square via shuttle bus?

You may take a free shuttle bus to Sands Hotel from Venetian. The buses are available from 10:00 to 00:00, and the frequency is 5 to 15 minutes. Upon arrival, walk west for about 1.2 miles to Senado Square.

Or, take bus line 26A from Est. Baia. N. S. Esperanca/ Istmo Station to Almeida Ribeiro/ Weng Hang Station. The fare is MOP 4.2. Upon arrival, you can see the square. ;)
