I've got a Dover -Calais ferry crossing booked for next Sunday at 11am. It would ordinarily take 2hours to drive from home to Dover. So would normally aim to get to Dover for 9am, I'd leave at 7am.
But if the traffic is going to be horrendous (seen stories of people queueing for 5 hours!) I'd have to leave the day before! Would staying in Dover overnight help avoid the queues?
Or do you think it might have settled down by next weekend?
