A good question.
A local answer.

A suburban centre suits a broad indoor retail selection and straightforward parking. Check current shops if a particular brand matters.

Compare the boat's departure and return times with a bus or car route, especially if you want a full day at the sanctuary.

Compare daily travel times from a central hotel with the cost of a larger rental and parking. A cheap distant stay may consume the week in transfers.

Check the current ferry route map because not every wharf is served by every service. Plan from the exact wharf names.

Check luggage storage and checkout time if embarkation is later in the day. One relaxed neighbourhood is enough for a short pre-cruise stay.

Consider a guided nature day for places with poor last-mile transport. Compare actual time outdoors with the time spent on the road.

Check the airport's current overnight access, lounge hours and shower facilities directly. Do not assume an old forum description of a lounge or terminal is still accurate.

Base each part of the trip near a useful station or tram stop, and avoid changing accommodation for every attraction.

Check the passenger ferry, island bus and return connections as one itinerary. Five hours can work for one area, but not for a circuit of the whole island.

Work backward from the ship's all-aboard time and keep a buffer for traffic and queues. Check ferry service notices on the day.

Pick the outing by the entire return route, not just the outbound train. Check the official planner for weekend frequency and the last convenient service.

Check the airline's recommended arrival time and the airport's overnight access before deciding when to leave your hotel.
