Maybe O'Sheas limited the tournament to one particapant per houshold so more people could get an entry strike instead of having to try to get one off ebay or from other sources at a higher cost and then maybe it was to keep from giving double comp room nights to a couple who both entered, just think a couple might get 6 comp nights and not have to pay for a room if they were staying for the convention, I am sure that the fine people at O'Sheas thought about this. I am also sure that the husband and wife who both want to play will figure a way around this rule, If I was attending I would just use my mother-in-laws address for my wife have two rooms and one could sit empty or I could sub rent it.
So you people who are thinking this is unfair, just put on your thinking cap and find away around the rule so you will have an extra entry strike to sell.
