We end between 12 and 1 as the elderly members of our Seder can’t go much later than that. A late Seder for the sake of having a late Seder would defeat the purpose. Judaism is not a religion of competition. There is no need to be better than anyone else, certainly when “better” is determined by something as subjective as who takes longer to talk, read, and eat a meal. It’s possible for some to have a more meaningful Seder in two hours than others have in 6. And it will almost definitely be more meaningful if the goal of that 6-hour Seder is solely for the sake of saying, “My Seder lasted 6 hours.”
Oh, and, needless to say, I will not compete.
