I'm taking SeaFrance at the weekend. £56 return. I'm too lazy to do a search and save the odd £5 and it's a ferry not a cruise liner so as long as it doesn't sink or the crew don't damage the bike that will do for me.
I did it yesterday as it happens.
Dover to Calais but also threw Portsmouth crossings into the mix.
Add some unfathomable debit card problems and it took 3 hours in total.
A marvellous way to waste your life, guess I need to invest in some staff.
