Thanks for the right locale.
Whoo booy. Bring a DS/PSP/Something because, depending on when you show up. I guarantee you will be in line for 3-4 hours.
Make sure everything is fully charged too, otherwise you run the risk of being trapped in creepy conversations with guys who idolize Heero Yuy or my personal favorite - stuck behind rather unattractive cosplayers engaged in Public Displays of Affection.
*shudders at the thought of the last one*
