This is why we have a whole thread about recruiting a bunch of people from here who have read about this plan. A problem for us if we manage to have enough people signing up is to actually have everyone get into the kingdom quest. If some of us misses out, then that's a problem. But if we have the majority of the group in there, like you said, everyone will run off to their own gates and the minority should follow different people.
Say, we have four groups, but each group is missing one person or something. As soon as KQ starts, the leader of the parties that are pre-organised will quickly invite the names that we don't recognise (the ones who weren't part of this), and those people should be following their party. If they don't, the party can always tell them to.
