19. Sea cruise (Portsmouth-Caen)

Rather than choosing, like everyone else, the Dover-Calais ferry, whose crossing takes 1h30, we opted for that of the Brittany ferries company, which notably offers Portsmouth-Caen. The journey is longer, almost 7 hours, but the price is lower, the cruise (because really, it is one) is very nice and in the end, we saved several hours of driving, fatigue and fuel .
