Is ten days in Adelaide worthwhile for a long-awaited return visit?

Plan for jet lag at the beginning and leave a final buffer before the long return flight.

Group one or two regional excursions between quieter city days to avoid spending the whole visit in transit.

Ten days gives you time to revisit familiar neighbourhoods and explore at an unhurried pace. Keep several days flexible for people, memories and local outings rather than filling every day with a distant trip.
