I'm planning a very small engagement party at the end of the month. Its just our immediate families and the wedding party (which is only 2 friends each as the party is mostly siblings). This is mostly an occasion for the families a wedding people to meet. I'm only calling it a party cause I've been wanting an excuse to do a Haunted Mansion/Aadams family type Hallowe'en party. Mostly it's going to be a bit of themeing in some decorations and food.
Does anyone have any suggestion or ideas that they've seen at similar gatherings that they liked? All those "learn about the bride and groom" games are sort of redundant as everyone present knows both of us. I'm mostly looking for some plan Bs in case of awkward silences.
