I voted 1PM. I actually think the best way is to wake up an hour before the store opens.. get there exactly when it opens in the morning, and inquire about lines, if there aren't people there already. Then if it's clear, leave and come back in 2 hours. Then the closer it gets to the time, I may just sit in my car and wait it out. 12PM to 6 doesn't seem too bad.. I mean it's a lot of time, but it's worth it, no?
