We find that while you are eating more on a cruise, you are also much more active. Between the shore excursions and the constant activity on board, you are always active. We do gain a couple of pounds but they quickly come off when we go back to eating normally at home.
Although we eat at the early seatings, so maybe there is something to having to eat let and then sleeping on it.
