Suggested Itinerary in Macau for 2 days

If you arrive there at the the airport, you go to your hotel directly. At your hotel, you can find free shuttle buses to reach the Sands. After you visiting the Sands, you can go to the Fisherman Wharf to have a visit.
From the wharf, you can take bus 15A to reach Ama Temple. After that you can take the same line to reach Ruins of St Paul and then visit the Monte Fort and Senado Square.
Then you can walk along Avenida de Almeida Ribeiro to find the free shuttle bus of your hotels to go back.
The next day, you can take the free shuttle bus of your hotel to reach the City of Dream where you can have a short visit. Then you take the free shuttle bus to reach the Macau Tower. After finishing that, you can take a taxi to reach Avenida de Almeida Ribeiro to visit the attractions that you did not visit the day before.

Thank you for your advice.
