Hallowe'en Games

Scrabblette, the kid and I are going to a gaming Hallowe'en party on Saturday. What should I take?

The Arkham Horror - a very good game if you're willing to spend 3 hours or more. Theoretically I would have more hours than that, but can I depend on the concentration span of the players?

Lexicon, Scrabble, Boggle, Milleranagrams - good fun to play with Scrabblette and the hostess of the party.

The Great Dalmuti - a good party game, though Scrabblette isn't into card games so much. The host has a decent selection of party games.

PitchCar - always good for large groups, and will keep 8 players occupied.

Betrayal at House on the Hill - despite the bad rules, a great experience game. Not too long, and always interesting.

Fearsome Floors - I think it's about time we started playing with the advanced obstacles. Not a deep game, but one that allows good player interaction and takes a decent number of players without lasting too long.

Gloom, Unhappy Homes - I've owned the (first) expansion for a long time and never played it, so I think I'd better take it along.

Goosebumps - I have a selection of Goosebumps games, none of which I enjoy. So despite them being appropriate, I'll probably leave them at home.

Mystery Rummy - I have 3 of these games, all of which I like, but Scrabblette is not into card games. Can she be won over?

Nacht der Magier - What better Hallowe'en game than one that's played in the dark? I do like playing games in the dark with Scrabblette.

Any other ideas? Here's what I own.
