We will have one large/checked bag that we will need to store before and while on our Rick Steve's tour in June. The best place for us to store and retrieve that suitcase is at the Zürich HB. The sbb website shows a luggage storage location on Floor 0, but it can't be reserved ahead. Is there a chance that they would be full and unable to store our bag when we arrive?
Has anyone used this storage location? Experience? Recommendations?
Thank you for your help!
