So it turns out that we got the worst front desk supervisor ever when we were trying to check in. The manager I spoke to was able to identify him immediately form my description and I got the feeling that he was going to get a serious talking to, particularly since we'd asked what our parking options were and he just sent us on our way to find some for ourselves. She wasn't very happy with him.
But she did all the right things. She made sure that we weren't charged for anything and offered free valet parking next year at the Con, or any time that we visit her hotel. She was very nice and actually sympathetic and kind of pissed at the fact that her staff had blown it. Overall, I'd have to say that she was extremely helpful. And if we go to the con next year and run into a problem with staff, we'll definitely be asking to see a supervisor immediately.
The sad part is that I still haven't heard anything from the con liason. Norwescon staff appears to suck worse than hotel staff.
