Quite agree mondo, although we have done both routes many times and now with a 8.7mt x 5000kg motorhome doing 20mpg I did give some serious looking at the ferry again for our trip with 3 others to Spain in April 2013.
Ferry one way £397 (always drive back) plus £200 fuel from ferry to Crevilente
Driving 1500 miles avoiding tolls as much as possible £450 + extras for overnighting, so driving there and back this time, I love the driving bit and intend going the Col de Portalet this time as we went the Col de Somport last year.
