Travel to Macau

First of all, congratulate, hope you will have sweet anniversary in Macau.

Macau is not large and most of hotels and casinos do have free bus, so you could take a easy trip here.
1. From airport, there are shuttle bus running to downtown Macau. It is also not far to take a taxi.
2. I think you could book the Venetian resort, which is a large comprehensive commercial centers, including luxury hotel, restaurants, brand shops, entertainment centers and gorgeous tourism resources. This hotel has free bus transferring you to and from airport, ferry terminal and city center.
3. First of all is the Venetian, Senado Square, Ruins of St. Paul, A-ma Temple, Macau Tower, Hotel Lisboa, City of Dreams, etc. You could visit the official website of Macau Tourism Bureau for details. As for food, you should choose a quality restaurant for Portuguese and these local dim sum. On the Rua do Cunha, not far from Venetian, there are many shops selling authentic souvenirs of food.
4. From Venetian, you could take free bus to Gongbei Checkpoint, walking through which you could enter into Zhuhai. In Zhuhai, you could see the Statue of Fisher Girl and then walk along the Qinglv Road along coast.
5. From Macau, you could take a ferry to Shenzhen directly in one hour.
6. I think you could have a dinner at the revolving restaurant on the 60th floor of Macau Tower.
