Thanks to you all, we have our two-week September trip pretty well planned. The majority go the trip will be spent in Switzerland. However, riding the Bernina Express is a priority for me [regular train], and our Plan A fits well with going over to Varenna for a few days.
IF the current covid restrictions stay in place, we won't be going to Italy, so need a Plan B. We are British Airways flyers, [the husband insists] and the west coast flights go thru Heathrow. Currently Italy won't let travelers going thru Heathrow enter without quarantine. We are fully vaccinated seniors.
So- We will be coming from Lucerne and want to ride the Bernina Express route. Do we have options beyond riding south to the end of Switzerland and then returning the same way? [This might be fairly relaxing, actually.] We are considering then staying in Pontresina, perhaps. Rick isn't too enthusiastic about staying in Chur.
After this leg of the trip, we are going to Murren. [Have been to Zermatt and Lugano.]
We have purchased the discounted Swiss Travel Pass.
We still have about a month before making any decisions regarding canceling [free] the Varenna hotel.
Thanks so much for the invaluable help offered so generously here.
