Hi There,
I driven down to Alps for past 20 years+ either with friends or alone. I'm here at the moment in fact. Also flown out mainly in winter,or as a quick return to the Uk for a week or so then back to work out here.
The drive from Calias, Dunkirk is cheaper option,I normaly use auto routes,with tolls so from Calias to Cham this year 2015 was around 8o euros in tolls Sanef tag very usefull,as stated, as the payment tolls are on passenger side and some now are un maned so you will have to get out of the car to pay,iether cash or card,I fill up the car in Dover and get here with fuel to spare,diesel,ford focus estate. I have been to known to do it in a one'er but it doe's trash you,and not to be recomended. Early ferries are cheaper,think mine was at 17.50pm with P+O and I was on the other side with a good few hours of driving in daylight, had a good snooze in the car and was in my appartmet in Aregentiere by 10 am.
Good points made with car are that you can move around, get out of the valley if the weather is crap or you just want a change of scenary,believe or not there are other areas in the Alps other than Cham that are well woth a vissit.
For me the car is a necessity,transporting clients and gear.
If alone,just take loads of breaks,snooze time, the auto routes as mentioned are boring as hell.
Have a safe journey what ever method you use and enjoy the Alps.
