The invitations are worded "and guests." If Ellen wants to bring Marcus, then please do so. The party is totally casual and anyone in the group is welcomed. There's no one at the door checking off a list, so even crashers are welcomed to attend. The only rule is that no one is allowed to wear ice blue or anything snowflakey.

Leave any other questions at my homesite, please. Thanks. More information will be added as the party gets closer and that includes pictures and descriptions on everything. Until then, don't forget to leave messages at my homesite.
