A good question.
A local answer.

Group nearby stops on the same day; returning across the river repeatedly can take more time than the map suggests.

Choose one walkable river or parkland area for each free block rather than spending the short trip crossing town.

Do not plan to walk from the lookout to a city hotel after dark; arrange the return before sunset.

Roma Street Parkland can make a compact visit near the station, while the riverside route offers a broader city view.

Group City Hall, the museum and parkland stops by walking distance so teenagers are not spending the day in transfers.

If time is limited, enjoy one central garden well instead of spending most of the morning reaching a second.

Look for the shortest level route to the main lookout and confirm whether the viewing area has seats and accessible toilets.

Check current event listings for your dates. A local performance or market can make an evening more distinctive than another long drive.

Combine South Bank's riverside paths with one nearby gallery, garden or café stop rather than leaving the city every day.

A suburban centre suits a broad indoor retail selection and straightforward parking. Check current shops if a particular brand matters.

Choose one regional day by interest, such as wildlife, coast or hinterland, and leave the third day flexible for weather or work preparation.

Check the conference finish time before booking a timed attraction. An evening ferry ride and meal can fit better than another daytime tour.
