My family (with 2 small kids) will be arriving in Chicago (on a sleeper) on Sun in July and are connecting to the Pere Marquette. I just got a message stating that our Business Class was cancelled and we will be in coach now for that segment...which is fine...however does that mean there is no longer Priority Boarding for us? Just nervous we may not find seats together! From other posts it looks like we might be able to go to the special boarding area as we have kids. If that is our only option would one of you amazing seasoned travelers be able to tell me if that’s the south boarding area? 1st time to this station...and hoping not to get lost with kids and baggage and all
