A good question.
A local answer.

Allow time to find the platform and board; do not base the plan on an old description of the surrounding streets.

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.

Save a backup direct-ride option if the last suitable bus leaves before you finish the visit.

Book a return arrangement or check the last practical service before entering the sanctuary; the outbound trip is only half the plan.

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

Plan a short out-and-back river section so the car is not left longer than the ticket allows.

For a brief stay, prioritise a comfortable room near your main activity over crossing the city several times.

Pick accommodation and transport around the dinner if you want a relaxed evening without a long trip home.

Choose a few dining areas near where you stay and review current menus rather than relying on a single dated restaurant name.

An evening dolphin program may finish after a normal day-trip return. Verify eligibility and timing directly with the operator before booking.

Wildlife sightings are never guaranteed. Pick the island whose accessible beaches and walks you would enjoy even without an animal encounter.
