Hallo Superbmum
I don't think it is a full winter in Nov. But then again winter may come earlier this year. For me it is not that cold in the Swiss town cos I have been to colder places like the artic circles. But the mountain can be a bit of challenge if you are not used to it. I think temp in the town should be around 5-10degC normally.
For kid, better bring warm clothings & it doesn't mean just by wearing more it be warm. A layer of long john & those ski suit for kid works pretty well. If need to a layer of flees/wool pullover can be added before the ski suit if not too warm.
For adults, you need to dress correctly. Usually, what we did, wear a 1st layer of good long john (pure cotton material is good. wool is better if you can stand the 'itchness' on your skin). Follow by a 2nd layer of flees jacket or pullover. Finally a good winter jacket that is 'wind proof' to be the outer layer.
That's for the body. For the legs, after wearing the long john, a pair of ski pants will do the trick if it is real cold. For me I usually wear jean.
For the feet, wear gd thick cotton sock, double layer if necessary & a pair of waterproof shoes. Leather shoes or boot will be good. Track shoes are certainly out.
For the face, use lots of moisturiser esp for girls (man also lar). Use ear protection against the wind & beanie is good to cover the head. Scarf will also be good but I find it more like accessories.
For the hand, use lots of moisturiser also cos it will dry & crack & its painful. A good pair of ski gloves is the best protection.
For accomodation, search & book thru the Net. You will find cheaper rate then walk-in. Stay near town central if possible to avoid travelling. Can be bad esp in winter.
Shopping, actually nothing really interest us there. Some glass stuffs look intersting, like barometer & glass balls thermometer etc. Clothings etc you probably won't find much cos it is winter & selling only winter stuffs.
Wah.... look like a long reply....
