WengenK—- I did originally book the direct IC train from Luzern to Milano, the 12:18 IC151. I noticed it was taken off the schedule after the tunnel closure. So I booked an alternate route, changing to a lakefront hotel in Weggis that I like. We will take the boat down the lake and meet the Treno Gottardo at Flüelen. Since we have a party of 8 people traveling, including 2 children, and we are not boarding the train at its point of origin, I deemed it prudent to get reservations so we can all be in the same car.
The last time we rode the Treno Gottardo (one year ago) there were 2 Swiss women in the 1st Class car who had seat reservations (we happened to be sitting in their seats as we hadn’t noticed the reservation cards). They politely asked us to move, and we did, and then had a very enjoyable journey chatting with them in mixed German, English, and Italian. They were curious how we, as Americans, even knew about that train, and pointed out the scenic points as we passed, like the little church we was 3 times as the train made switchbacks up the mountain.
I emailed SBB about a refund for our original tickets, and by that time the 12:18 IC train was only canceled in early September. They said if I want a full refund I should wait and see if the IC151 is canceled for our actual date of travel later in the month. If not, we can still get a partial refund as usual. Looking at the schedule now, I see the IC 151 is only missing from the schedule on 6 September. So I will just apply for the partial refund.
The tickets we have from Bellinzona to Desenzano include the bus link, but reservations are not possible for the bus or the regional train from Milano Centrale to Brescia.
