Thanks for your trip report on the Christmas markets, I enjoyed reading it, and have added quite a few of them to my "list" in case I am in Switzerland at the right time of the year on a future trip.
Sorry to hear about your sight problems :( The Christmas markets are so atmospheric at night - what a shame that it affects you so badly. However, it is clear that you had a great time regardless, which I am glad to hear!
I was also back in Switzerland around Christmas, from 21 December to 26 December, and went to the Christmas Markets at Zürich Hauptbahnhof and Luzern Bahnhof. I must admit I prefer the outdoor markets to the indoor ones, but there's something to be said for being under cover in inclement weather! As you mentioned, the market in Luzern Bahnhof was very small. Apparently there was another market at Franziskanerplatz, but it had closed the day before we were there. The Christmas lights in the Zürich Bahnhofstrasse were lovely, but we had to go back to see them later in the evening, as they hadn't yet been turned on when we first went looking, around 4.30pm after a cruise on the Zürichsee.
>> After wandering again we returned to Biel where Mike discovered he had left his spectacles behind in the restaurant – yet another mishap with spectacles! The hotel receptionist phoned the restaurant to see if they had indeed found them which they had so Mike had to hurry off by train back to Bern to retrieve them!
I remember the last incident you described as well, and I have also witnessed remarkable helpfulness from the Swiss in similar situations.
When I was boarding the train up to Pilatus last August, the person in front of me dropped her sunglasses onto the track below the train. She looked so disappointed, but was resigned to the fact that they couldn't be retrieved. However, after the train left, one of the staff picked the sunglasses up from the track and brought them up in a following train, handing them back to her at the halfway stop!
Then at St Moritz, I was waiting one morning with several other people at the bus stop outside the Youth Hostel. We all boarded the bus, which then does a U-turn just past the hostel to go back into the main part of town. That meant we drove past the stop where we had just got on, and the driver saw a pair of sunglasses sitting on the seat at the bus stop. He stopped the bus and called out to the passengers to see if the sunglasses belonged to any of them. They did, and the person jumped out of the bus to get them before we continued on our way!
And finally, an incident that affects me more closely! My (adult) son accompanied me on my Christmas trip to Wengen, and left his backpack on the train when we were changing trains at Lauterbrunnen. We had already boarded the Wengen train on platform 4 before he realised. The train we had arrived on was still sitting on platform 1, so he jumped off the Wengen train and raced back to platform 1 in the hope of retrieving his backpack. Meanwhile I got off the Wengen train with both our suitcases in case he didn't get back before it left, which was pretty likely!
As he arrived on platform 1 and jumped onto the train, it pulled out on its way back to Interlaken Ost! Luckily he eventually found the right carriage and retrieved his backpack: but was now on a train heading in the wrong direction - and without a valid ticket, as we had been using point-to-point Supersaver tickets for our journey from Luzern to Wengen!
The conductor was so kind and helpful, even to the extent of ringing the conductor on the train my son would have to take back to Lauterbrunnen from Zweilütschinen, to ensure that he could travel back without any problems due to lack of a ticket.
Eventually he arrived back at Lauterbrunnen (thank goodness for the frequency of services!) and we continued our journey to Wengen. As our Supersaver tickets were no longer valid, I had to buy additional tickets from Lauterbrunnen to Wengen, but they were not expensive, and the purchase was easily accomplished in the SBB Mobile app while sitting on Platform 4 waiting for the next train to Wengen.
The Swiss really do look after their visitors!!
