After customs clearance at Gongbei Port, when you leave the gate, there is a free shuttle bus to the hotel on the left. It takes about 20 minutes to reach the Venetian Hotel, and it should take about 3 hours to visit, shop, eat (the famous Andre Egg Tart Hotel has a branch) and take photos in the hotel. After getting off the bus, you can take the free shuttle bus to Jinsha Hotel (the shuttle bus may pass by Sai Van Lake Square, the venue of the food festival (where the sightseeing tower is located). After enjoying the perfect food, you can walk (about 40 minutes) or take a bus or taxi to Xinma Road, which directly walks to Dasanba. There are old city walls, artillery company, Macao Museum and other scenic spots around the Big Three Dam. You can play slowly for a while, then go back to Xinma Road, take No.5 or No.3 (if you want to cross the road, look at the bus stop sign and pay attention to the driving direction), go back to Guanzha, then go through the customs and return to Gongbei Port. Have a nice trip.

I just checked the schedule of the food festival. The food festival should start from 5 pm to 1 1 from Monday to Thursday, and from 3 pm to 12 pm on weekends, so I still suggest going to Xinlu before going back to the food festival.
