I propose travelling by car to Le

We have friends that have done this at least the last 10 years, mostly at that ime of year and never had problems.

You shouldn't have any real problems if you stick to autoroutes/main roads.  I see you go via Colmar, I'd get there on the main route [autoroute via Strasbourg] rather than 'over the top' [Nancy to Colmar.Otherwise, no probs  

My other suggestion is, if you have a little time to spare, is o go via Luxembourg. It costs about an hour [max] in travel, but is toll free, and you can also fill up in Luxembourg at the services with very cheap fuel

That sounds like a good option. Thanks again. 

I came down a few weeks ago. Belgium Germany Past Munich down to Austria and into Italy that way. Only toll i paid was when i.d had enough messing about in Italy so jumped on the toll top end of Italy. Basically free motorway all way . Bit snowy going over Austria but no trouble

I think that at that time of year you SHOULD be okay weatherwise, motorways generally are cleared pretty quickish if there is snow, if necessary take the motorway and take the hit of the fairly minimal toll costs.Br

Thanks. Fingers crossed weather should not present any problem. 

Dont forget your snow chains. Certain times of year. If you havnt git them in the car it aparently can get dear with the fine. Especially if you have a prang

We came back from Italy end October and it was snowing heavily on the motorway either side of the Gotthard tunnel. I recall seeing a sign that said winter tyres were needed from November onwards and read somewhere that you can be prosecuted if you even hold up the traffic due to being ill prepared. Despite the snow ploughs and having a 4 x 4 I found the motorway quite treacherous - best to check when the winter tyre requirement goes to.

Good point - many thanks.
