A good question.
A local answer.

Choose one wine-region base on the way back and keep the other days for short, nearby outings.

Ask what the package includes, the arrival deadline and the final per-person price before paying.

Check the market's current parking guidance and height limits, then look for a legal open-air space sized for the full vehicle.

Adelaide can anchor city dining and nearby wine outings; list the exact wildlife and beach experiences you want before choosing a base.

If time is short, choose a closer bakery and save the longer detour for a day with another nearby activity.

If the goal is a relaxed winter trip, spend longer in fewer areas rather than moving accommodation after every outing.

Decide whether coastal scenery or inland towns matter more, then map actual drive hours between overnight bases.

Allow for winter weather and daylight on the drive back; a boat outing may have separate conditions and cancellation rules.

For a change of scene, choose one coastal or hills outing and check the full public transport return before leaving.

Check Haigh's current tour booking rules, opening days and age guidance before heading to Parkside.

Allow weather and match-length flexibility rather than booking a tight dinner immediately after play.

Check the current store directories for brands you actually want before spending a half-day on either trip.
