Hi! We originally planned to side trip to Macau on our Hong Kong trip but the agency got our itinerary mixed up thus we end up going to Shenzhen. May I just ask if it is possible to go to Macau on the early morning of July 12 and be back in Hong Kong after lunch coz our flight will be 7:30 pm on the same day and we need to be at the airport around 4pm. How much time should we consider in going to the airport from Macau? thanks.
