Yes, on Trans Atlantic we'd plan 6+ Sea Days straight on Cruise. Me, Love my Seas Days and only do longer 10+ niters long Carb and Repos myself(SOLO) with 5 to 5, 4 to 6, 5 to 6, 5 to 8, Port Days and Sea Days. But for my Daughter and Grand Daughter on their first Cruise longer then 10niter this 16n ended up being 12 Sea Days as we lost 3 Port Days.
