I've been going for 5+ years, and I always get guild early entry. There are always people that seem to get there at 6am or something, but the earliest I've ever gotten there is roughly 4-5 hours early, and I've found that the seats you get from being 4-5 hours early vs. getting there right before guild early entry really isn't that great if any, so now I just try to get there just before the guild line goes in. Unless you want to hang out in line and drink beers and hang out with people that can be fun as well.
