A good question.
A local answer.

Book a meal ahead or keep food with you because holiday dining can be limited.

Read recent room-specific reviews for service and noise.

Confirm the payment or top-up method at the airport station.

Compare current operators by departure point, activity inclusions, equipment and weather policy. Choose one that coordinates the ferry and leaves enough time for both activities rather than booking them separately without a buffer.

Check whether the pool has child supervision rules and seasonal maintenance.

Compare current door-to-door fares and journey times for your exact arrival hour. A train or bus may suit light luggage, while a licensed taxi can be worth the convenience after a late flight.

Plan for warm, humid conditions and possible heavy rain, then keep beach and nature days flexible. Check surf and weather each morning rather than relying on a monthly average for a particular day.

Choose a property with a flexible cancellation policy if the access details cannot be confirmed in writing.

Break the route into a few chosen regions and compare rail, flights and small-group tours instead of expecting one short package to cover every coastal stop. The distance is substantial, so allow enough days for the places you value most.

Read the provider's current storage-location, handling and damage-claim terms before paying. Photograph the vehicle at handover and collection, and compare valet with self-park if the location matters to you.

Confirm ferry, park access and vehicle requirements if planning independently.

Save the terminal address and return-area directions offline in case navigation is confusing.
