Edit: gavra, vorts can be anywhere from “extended l’chaim” to hall with hot food and music +. To play a slight devils advocate, a vort at home is not always feasible depending on setup, timing etc.
Next thing you will tell me is that Shiva “at home is not always feasible depending on setup, timing etc”. There is no reason to make a Vort whatsoever, let alone spend money on it.
