I don't think you can do a fair swap if you are going by days stayed there. You basically want a free holiday for a few days but don't want the other person to really benefit. You said so yourself it would be pointless to go unless it was at least 5 days. Simple don't do the swap or plan it so you stay longer at the other persons house.
If they stay 3-4 days at our place they'd be getting $1-2k+ worth of accommodation for free. So I wouldn't say they are having no benefit at all.
