what transportation to take from senado sq/ruins of st paul to venetian?

hi,
i'll be travelling to macau during peak season and seems it will be hard to get taxi/bus,so i need your advice which one is easier for my route (venetian, senado sq, ruins of st paul)
A. arrive at ferry terminal, take shuttle bus to venetian. after that queue up for taxi to senado sq-> st.paul . going back to ferry termina by bus.
B. arrive at ferry terminal, take bus to senado sq-> st paul, than take taxi/bus to venetian. going back to ferry terminal by shuttle.

since i'm not sure what transportation to take from senado sq/ruins of st paul to venetian, pls also needed your advice.
tks a bunch
