The Wessex Expansion adds a fifth family board to the mix that gives the advantage of a larger starting country estate. A player selecting the Family Wessex player board will have their choice between the Breakfast Room and Tennis Court, second level improvements, in his or her manor house at the beginning of the game.

The expansion also adds five additional Starter Guests, five additional Casual Guests, five additional Prestige Guests, and six new Solitaire opponents.
