I had fields in there because on a -100°C ice sheet you don't get to keep everything warm enough to accomodate guests, so I just put up some beds next to the indoor sunlamp grow op.
On another note, if you sell a bunch of totally disabled (no legs, mostly) people to a caravan as slaves, the next band of visitors will immediately come rushing in, pick them up and say "They don't wanna visit you anytime soon" and the "They're taking home wounded comrades" thing. Doesn't matter if you kept them fed and healthy in the meantime.
