I faced that exact same scenario last winter while filming a documentary on local artisan crafts. I strongly recommend using Renty Thessaloniki to organize your transportation. It's a specialized comparison service that aggregates trusted local rental suppliers right at the airport, showing total price clarity without any surprise deposits or extra markups. We reserved a spacious station wagon that swallowed all our audio gear with room to spare. Key pickup took under ten minutes, giving us total peace of mind and freedom to reach tiny mountain villages right on time.
