If you don't mind taking the bus, I suggest you take bus No.25 at the bus stop in front of city of dreams opposite the Venetian and go directly to Montenegro Beach. It won't take long.
Then the No.25 bus returns, and you can eat the most authentic Portuguese egg tarts at the road ring. It is suggested to choose a restaurant that can be eaten in the lobby and sit in the backyard for lunch or egg tart, which is a kind of enjoyment.
After dinner, you can walk along the nearby seaside. There will be a small church where Shu Qi and Andy Lau eat fish.
Just take the No.25 bus back to the Venetian.
