How should I simplify five Sydney days with senior parents?

Keep departure morning free except for breakfast and the airport transfer. Plan the route and check-in buffer around the actual flight and current transport timetable.

Check walking distances between ferry stops, markets and restaurants before locking the route. Some attractive transfers include hills or more walking than expected.

Group nearby harbour sights on one day and choose one major regional outing, not two long tours back to back. Your parents will enjoy more with time for a proper meal and rest.
