Port person here. A ship is just a way to get from one to another and I don't have to unpack.
Balancing, I do love at-sea days. I think the most relaxing cruise I have ever done was the trans-Atlantic on R IV. Then it got crazed with port-intensity.
Best cruise ever was in the PacRim where the cruise line balanced a port day with an at-sea day even if the ship did have to stooge around out at sea.
Loved it !!!
