Hi Jonny., Worth a look is run down to Rosslare ( I live the other side of the Foyle) I allow about 6hrs without rushing. Go accross to Pembroke Then down to Newhaven Sussex There are 4 boats a day to Dieppe run by DFDS and take 4 hrs to cross .Very good prices and not as much hassle as Dover You dont need cabins on any of these crossings and no diesel in U.K.
Newhaven - Dieppe is a good choice, especially if you are over 60, as there is a 20% discount available on that route if you book by phone (over 60's concession fare offer is not available online).
Just choose your crossings and then ring the 0800 number to book.
See concession fares here.

If you book the 10am crossing you can get all the M.25 bits out of the way when it's quiet and then just park up outside the check-in booths at Newhaven - last time I went there were 6 vans spending the night there.
Both Newhaven and Dieppe are far nicer places to travel through than Dover and Calais.
From Dieppe there is a fast, empty and free dual carriageway nearly all of the way to south of Rouen.
