I went to the Classic on Transmanche from Newhaven to Dieppe. It was a brand new boat, the food was top, the service in the bar was instant and the crossing generally a huge sucess. The advantage of Newhaven is that it's only 25 mins from my house and drops you in France 165 miles from Le Mans, all motorway or dual carriageway notwithstanding Rouen which is a big fuss about nothing. Cost £50 return, the bargain of the century if you take fuel costs into consideration, it's cheaper than Speed Ferries.
Came back on LD for reasons I won't bore you with. Not as impressive as TM, but not bad, it was about on time, the food was fine as was the drink. It was about £70 for a last minute single, which is about half what it would have been when the ship was under the command of P&O.
Generally very satisfied with both operators, so I don't think I'll be using Brittany Fisheries again, their £350+ fares are really getting beyond a joke.
