It's worth trying there, but the wait can sometimes be long there.
I needed to get my new annual pass activated there in November.
Since I needed the pass to get in, I had no choice but to wait there. Because the people at the windows before me had complicated issues, it took more than 20 minutes before it was my turn - and there was only one person ahead of me.
I felt bad for the people behind me because it took quite a while uo solve my issue.
