Hello, I am new to these forums so thanks in advance for your help and patience! Our family is planning an eight week road trip around France and Italy this coming fall. We need to be in Paris for October 31st but want to spend a few days around Colmar/Verdun before arriving in Paris. We will be in Florence around October 22-25th (final dates to be confirmed) and I am wondering about driving through Switzerland to get to Colmar? Are Swiss roads generally safe to drive that time of year, or will there be mountain passes covered in snow? Should we drive through the Piedmont region of Italy instead, and then up the east side of France to Colmar, or does that put us around Mont Blanc with potential for equally snowy road conditions? I am not sure what to expect for road conditions in late October in those regions. Is there a totally different route I haven't thought of that would be a better option for Florence to Colmar?
Also I would love any suggestions on where to break up the drive for a couple nights? For most of the trip we are basing ourselves for about a week in each place but for this leg I'd prefer just a short 1-2 night break to split the drive in half. I realize this is a long drive, but its the only leg our our trip that will include a long stretch, just to get us back to our starting point. Thanks for any suggestions!
