A good question.
A local answer.

Check individual venue calendars for the exact weekend; regular live-music nights can change with private events. Look for band listings rather than relying only on a pub's general description.

Check Adelaide Metro's current concession eligibility and airport-bus payment rules before travel. An interstate seniors card may need an additional local process.

Check path grades, shade and the final return service. Leave one day in Glenelg for weather and a relaxed waterfront walk.

Contact motorcycle and scooter hire firms with the exact route, six-week duration and one-way return request. Many local rentals do not allow an interstate drop-off.

If you need step-free access or parking, check the latest official visitor directions before setting out. A nearby construction notice may concern the arcade rather than the market hall.

If the cash is for arrival expenses, consider how much you truly need to carry and whether an ATM at the destination is practical. Keep a secure backup payment method.

Confirm the current arrival platform, the Seaford departure platform and bicycle carriage rules with both operators. A timetable match alone does not account for unloading a bike.

Check the short-range forecast for each stop just before departure. Adelaide, the Murray and Tasmania can feel different on the same itinerary.

Ask each park about late arrival, dump-point access and cancellation terms. Keep one flexible night only if you are comfortable finding a legal alternative.

A wildlife park outside the city can use most of the short stay. Compare a tour with transport against a smaller city outing if the child will be tired after flying.

Choose one evening performance or tasting and make a reservation. Keep the other afternoon flexible if the organised tour runs late.

Use one full day for Barossa if wine and food are a priority. Decide between a designated driver and a tour before choosing stops.
