There is Macau Hotel Free Shuttle Bus at Macau Ferry Terminal. You just have to find your hotel in this website, and see the schedule of the shuttle bus to plan your trip!
We took the shuttle bus to visit The Venetian Macau. It is a 5 star hotel with Casino. We were not that interested in the Casino la, so we just walked around the hotel and admire the European style decoration.
We had our dinner at a Portuguese food restaurant in The Venetian. It was not cheap and the food tasted so so. I guess it's always not a good decision to have a meal in a hotel.
The next day, we went on a self guided heritage tour of Macau at the ruins of St Paul and Guia Fortress.
Look at the steps to climb!
After that we went to the famous Koi Kei to buy some almond cakes, egg rolls to bring back SG for friends and families.
We also bought a box of Portuguese Egg Tarts to eat on our ferry back to Hong Kong! Yums!!
In my view, if you are not a fan of Casino, Macau has nothing much to offer except the egg tarts!!
