I’m currently on the Best of Italy - we met in Varenna Sept 30 - so your time of year. We stayed in Castelrotto/Kastelruth for our Dolomite nights which were Oct 2/3. The hotel, Hotel Cavallino D'Oro, was really a charmer!
Our bus driver was able to take us all the way up to Compatsch for the hiking day which is not possible some times of the year according to the guide.
I saw where Hotel Seelaus is located and it is a great spot right at Compatsch but I can also see why both nights have dinner provided.
We arrived to Castelrotto on Sunday evening and there was difficulty with finding a place to eat on the arrival night. This was the guide’s first time back to this tour since Covid and unfortunately elected to take us on a short hike before sending us off to find dinner. The hike was nice but unfortunately when we got back to the town center we found few things were open, all were crowded or booked and some tour members didn’t get fed. One of my recommendations on the evaluation will be to do dinner both nights here as well or at least on Sundays for tours arriving that day of the week.
The online itinerary shows dinner both nights in this area but on this tour we were told the first night we’d have one group meal in Castelrotto and the next one in Venice.
This tour is excellent! I’m glad you are going to Milan ahead of time. Make sure you keep an eye on Last Supper tickets. I booked directly with them and booked the English tour thru the official site. It was excellent. I also booked the Fast Pass for the Duomo including the lift to the roof plus entry to the Duomo, excavation area and museum. I also went to the Pinocateca Ambrosiana.
Do you have a hotel picked out for Milan? I stayed at Hotel Gran Duca di York which is quite near the Duomo.
