Dungeonify this Haunted House

Coming in January, the bigwigs at Dicechucker Enterprises are throwing a bash in honor of 5 years of my life occasionally spent engaging in bloggomy.  For the event, the Powers-That-Be have rented a real, live haunted house on an island in the middle of the St. Lawrence River.  The island was once a fin de siecle summer resort for the wealthy, and is littered with gilded age mansions, but in the ensuing years it has become a disputed territory in the no-man's land between the US and Canada.  The island is claimed by Quebec, Newfoundland, Vermont, and Rhode Island as well as the Akwesasne Nation: dual US-Canadian citizenship, documented Mohawk heritage, serviceable knowledge of French and/or Kanien'kéha  language, snowmobiling experience, and ice-fishing skills may all be helpful in gaining access to the island.  Wearing the appropriate hockey sweater may go far to sway reaction rolls in your favor; though Maple Leafs or Bruins jerseys are not advised.

Given its status as disputed land, the island is a haven for smugglers and outcasts of all sorts, including the Bladerunners--a gang of kids who skate back and forth across the Fleuve delivering hockey sticks and illegal metric rulers to the south, then heading north with packets of hot cocoa mix and unpasteurized cheese curds for the poutine mills of Labrador.   Other factions in the vicinity include a Marxist snowmobile gang, Francophonic Sumo wrestlers, and a colony of rock candy sculptors

But, to the point:  The island is littered with grand old houses that are obviously too haunted for anyone's good. Attached is the floor plan, I'm looking for proposals to dungeonify this here haunted house. The top 5 entries will be granted directions to the island.
