I see that they will allow people to line up for camping the first day at 5 AM. I've never done this before but am planning to do so this year so I'm a rookie at this. If you can't be there until several hours later will you be placed far back in line or do you recommend getting there by 5 AM with others ready to be the first let across the street? Any other advice you can give for a first timer would be appreciated. Thanks.
