We haven't been on a trip West though Chicago since August 2016. SInce we always travel in a bedroom, our connection between trains finds us at the Metropolitan Lounge. In 2016 you just showed your ticket at the front desk, you made yourself comfortable, they announced your boarding time and guided you to your train. We have read of changes to the boarding protocol at CUS and are wondering if there any difference in the boarding procedure for sleeper passengers?
