We are from overseas, arriving at Zurich airport early morning with 5 luggage. We’d like to travel from Zurich airport to Grindelwald accommodation by train without dragging 5 luggage along the way, this will allow us to explore Luzern town and take panorama train from Luzern to Interlaken without dragging heavy luggage with us. We wish to book a luggage transport service from Zurich airport directly to our Grindelwald accommodation. I couldn’t find the luggage transport service I’m looking for at the SBB site (Zurich airport to door service-Express same day service). Any suggestion, please?
