A good question.
A local answer.

Map the real driving time with rest, fuel and daylight rather than relying on a nonstop estimate.

Check the airport's current retail directory and opening hours before assuming there is a staffed phone shop on arrival.

Book directly and confirm dietary needs, deposits and cancellation terms; ordinary restaurant listings may show last year's event.

Pick a central paid car park with clear height and luggage-security rules, then walk to lunch instead of moving the car repeatedly.

A city hotel can work just as well if spa time and a special dinner matter more than another regional drive.

Ask the actual rental company in writing whether its specific vehicle may travel on the ferry and whether the insurance remains valid.

Choose a single region for both open nights to avoid losing a day to check-out and another check-in.

If both adults will taste, arrange a driver or tour for those days and compare the full cost with a city base.

Compare a private driver with a small-group tour when the desired stops are fixed; keep travel time realistic.

Check whether the meal is fixed-price, how long the sitting lasts and whether transport from the accommodation is available.

A weekday or earlier session may feel easier than a peak holiday visit; confirm today's opening and prices before travelling.

Contact the airline's special-assistance team before flying and describe the exact lifting help needed after baggage claim.
