When I bought one by phone a few weeks ago, the CM was all set for me to pick it up in Dec. I felt better having something in my hand, so I paid the 4 bucks. So based on that, I would say “yes, 5 or 6 weeks would be no problem”. Not sure if you can go to any will call window, but I don’t see why not. They have you in the computer, it’s not like they have your ticket sitting on a table.
