Report Thursday Pre-reg line in Otakon 2009 Posted June 5, 2009 If you arrive well before the doors open, you'll be waiting a while. If you come after the doors open and the line is moving, the wait will usually be much shorter. Which is why, despite the opening time, many folks here on the boards who are familiar with standing in the Thursday pre-registration line suggest coming around 7-7:30pm. The line is never short by any means, but it moves faster and the sun's going down by then. Of course pre-registering is faster than registration at the convention. All you really have to do then is pick up your badge. If you're coming Friday morning and want to miss as little as possible, pre-registration's the way to do it.
