Summary of costs so far and more
France £253 12 days so weekly =£148 Plus Eurotunnel @£85 but this and the return cost needs to be shared !
Switzerland £774 for 25 days so weekly = £217
This includes the vignette and also the elongated stay at a camp due to the puncture
It does not include the puncture costs as that goes into the Yearly budget
It may be that I can clam most of the extra campcosts back
Thus maybe just under £200 a week including an excursion
Food,especially meat, is very expensive in Switzerland
Good beer from Lidl is cheaper than UK
Non camp-site overnighting is good and cheap or free.but.....
Disposal of black waste needs "planning" but there are free services on some motorways and other service points
(eg Leysin and some aires/stellplatz)
With 90 litres of Fresh water and grey water this is aspect is fairly easy
The M-way vignette is essential (IMO) as normal highways "turn into Motorways" with no alternative.
The passes we used were all fine just need care to avoid the tunnels.
We did not use the Furka or Susten passes as they seemed hairy in places.
The 2x St Bernards (Grand et Petit) were not on our route again a bit hairy I think.
We toured most of Switzerland the roads were good and the scenery etc brilliant.
Certainly worth a trip (say up to 1 month) and not "Budget Blowing".
Just my thoughts
