Hi I will be in Macao this Jan 31 to February. can you please suggest an itinerary?

Where do you start your trip?
If you start from the M Ferry Terminal, you can follow this plan: Fishman Wharf, the Sands, the Macau Tower, the A-ma Temple, the Ruins of St. Paul, the San Ma Lo. Then you can walk to the Sintra Hotel to take the free shuttle buses to reach the City of Dreams. Then you can walk to the Venetian to have visit.
I think you can finish the visiting in one day if you do not plan to gamble in M.
