I think the point was that not wanting a marine head isn't wanting "luxury" instead. I'd suggest that several things listed should be basic requirements like decent food, decent bed for more than a week and somewhere to get out of the heat. My recollection is that Deb's pricing wasn't top dollar but not bottom either. If I want to go on a boat where there's no hot water, I'm eating Top Ramen for every meal and sleeping on a bench, then fine as long as the price reflects that.
Clarification. There wasn't a problem with the food itself, just that it was often cold by the time you self-served. It wasn't a quality issue.
