Heh.
Well, I'd have to think twice before going on vacation on one anyway. One thing I know; there is nothing like being at sea to increase your appetite. We were well-fed on my sailing trip off Maine but not overfed. I was always ravenous. I know from my sister that they're constantly feeding you on cruise ships; she gained several pounds over a week. Of course, the booze probably didn't help, either. I'd have to spend 4 hours a day in the pool to work off the food and booze. I'd be a prune. 😁
