On invitations

Do people still ever have big dinner parties, and also weekend parties where they put their guests up in the bedrooms? Did those things only exist in old British novels? You set up such parties, send out invitations, and all your friends show up ready for you to show them a good time for an entire weekend? Though, of course, there was bound to be a ghost, or at least a good murder or two. Unless the novel was written by P.G. Wodehouse, in which case Jeeves would make sure that some young man won the heart of some young woman and escaped from whatever terrible predicament he got caught up in.
