SO in theory I am thinking of trying to get off in Paris where I have family rather than riding on until London ( I am doing the Barcelona to London Cruise) HOW can I do this? Has anyone done this before and has a trick or advice? are there reprocussions if I just walk off in Paris with my luggage? I want to do it the right way but have been trying to figure that out and can't find much info to help me move forward. I have until June....
