I was planning to book Express (same day) Door to Door luggage transfers between my hotels while in Switzerland. I understand that I have to do this 2-3 days in advance so I was trying to do it before we arrive in Switzerland. I have the transfers in my shopping cart ready to purchase, but when I try to enter my credit card details, it only accepts Switzerland or Liechtenstein billing address. Is there a way to purchase luggage transfers with a US credit card? Will I still be able to order the Express transfer if we arrive on 22nd and go in person to order the transfers at SBB station, but need the luggage transferred on the 25th? Thank you!
