A good question.
A local answer.

Shortlist neighbourhoods by the actual route to your research site and a supermarket, then compare furnished listings in those areas.

Price a one-day car hire only for any outlying stop that truly needs flexible transport.

Ask the hotel which exact room categories face the event area and whether a view is guaranteed in writing.

Compare public transport with a short car ride for the least convenient leg rather than assuming every sight needs a car.

Read the newest reviews for cleanliness, road noise and staff response rather than averaging years of comments.

Check the current food menu, kitchen days and tasting reservations directly with each cellar door.

Check road alerts and weather before leaving, especially if the trip continues into the mountains.

Treat peak colour as weather-dependent and check recent local garden or tourism updates near departure.

Choose the base by the walks you can actually reach and the season's road and park conditions.

Check the airport's current taxi rank and fare guidance, then confirm the hotel address before entering the car.

Check the club's current menu, opening hours, guest-entry rules and whether a booking is needed.

Map each property to your planned venues and consider how often you will make that journey.
