During our planned 2027 tour to Sardinia we are hoping to take a trip on the Bernina Express in Switzerland on our return route. We are hoping to find a nice hotel in Chur, Switzerland..take the train to Tirano, Italy on the 2nd day, with an overnight stay, and then take the return journey back to Chur on the 3rd day. Anyone have any information on 3/4 star hotels in Chur where they have secure parking for 3 nights, even though we will only be there for 2?
