Hi Vicky we did dover-calais this year and stayed in concarneau in brittany, the journey was horrendous although we stopped over night at an aire the drive took us 12 hrs leaving the site on the sat to make the ferry, we are going again next year, plymouth -roscoff sailing and we've booked already with select-sites (www.selcet-sites.co.uk) they were brilliant and as were going for 3wks next year and the extra sailing the price wasn't that much more. They are really helpful and have loads of advice give them a call on 01873 859876 good luck but definatley don't recommend the dover-calais especially if you have kids tracy
