The three tiers are for dinner price difference only. Everyone lines up in the same queue (no show seating priority). Even with the dinner package, people line up an hour before the show to get best seats, but even if you are farther back in the line, you will get seating (as long as you arrive about 15 min. before the show when general seating begins.
Hope that gives you something to think about prior to the official announcements for 2008.
