Is this for short trips or does the offer end on a certain date. I'm just looking to book our ferries for next year. Every trip we made this year cost us £38 return with Norfolk Line, I've been on line today and can't find a ferry for next year under £70 return. We aren't travelling in school holidays either. I ask because I've been on Sea France today and their cheapest ferry for us is £91..... thanks
