Hi! Me and my family is going to visit HK and planning a 1 day trip at Macau. We want to see the must sees attractions such as Fisherman’s wharf, Senado Square, Ruins of St. Paul, Macao Tower, Ama Temple, Venetian Macau and City of Dreams. This is our itinerary:
From Macau Marine Ferry terminal:
=>Fisherman's wharf: (10 mins. Walk from MMFT)
=>Senado square: (back to MMFT and take free shuttle buses of Grand Lisboa Macau to the hotel, and then walk to the SENADO SQUARE and RUINS OF ST. PAUL’S
=>From SENADO SQUARE TO MACAO TOWER and AMA TEMPLE: (??????)
=>From MACAU TOWER to VENETIAN and CITY of DREAMS: (?????????)
=>From VENETIAN to MMFT: (Venetians free bus to the ferry)
My questions:
1. Is there any free shuttle bus from senado square going to macau tower or ama temple? If not what should we take and how much it cost?
2. How close does macau tower and ama temple? how many minutes walk?
3. What ride should we take from macau tower to venetian?
4. And lastly, are these places possible to visit for just one day? If not, can you please suggest what we should give up? Please help me. Tnx in advance!
