In Montreux, the language possibilities blew my mind slightly - Most people were speaking French, but pretty much everyone was fluent in (at least) English as well. All the hotel notices were written in English and French, and often also Italian and Russian. When out and about, we would hear German, Italian, Spanish, Japanese and Russian all the time.
We travel maybe 70 miles north-east to the capital of the country, Bern, and it's all about one language - German. We just spent a few hours walking round the sights (what a great place!) and I don't think I saw a single French sign, and certainly nothing in English. Unfortunately my German is even worse than my French, but Helen has been teaching me some stock phrases.
Currently heading further north-east to Lucerne, where we plan to stay tonight.
