Dylan 4/2 - parking - no printed tickets?

When I picked up my will-call tickets for Dylan today, I was told that there was not a printed ticket for my pre-paid parking and that I would just need to supply my name to the parking lot attendant this evening.

Is this correct?

Should I bring my confirmation email just in case?

Confirmation e-mails are always great. Your name should be on the list of pre paid tickets at the lot.
