Pre-registration works exactly the same as regular registration (you just get some/all of your gifts early). We signed up for pre-registration since a group of us are going to do the Ft. Wilderness segway tour on Sat. morning. It'll be a busy day - segway tour, pin trading then the party.
Terry - normally dinner is served buffet style at least it was at the one party I attended (actually the first AK event). They usually have games of some kind, too. Between dinner, visiting, and games, the time will go very quickly.
