Two lines makes no sense - you'd have to have THREE lines (impossible) to accomodate those of us who have not yet returned or upgraded our tickets. I bought a ticket for the 23rd and I can't go on the 22nd and that shouldn't make me a second class citizen. I think the people who originally bought tickets (all 600 of us) to one of the two shows, should have priority, particularly those of us who bought tickets for the 23rd. It's only fair. I hope you figure ot a way to do this. The explanation on DCist makes NO sense.
