Take some time to look it over and mark the things you really want to do so you won't miss them later. If you're feeling industrious, work out your whole weekend schedule. Descriptions of all the videos, panels, and events can be found in the con book, so look up info on something you are unsure of. Taking a little time early to plan ahead will save you more time later, and you'll miss less stuff. It gets the prime Saturday evening time slot, and it is the most heavily-attended event at the convention.
Some people line up hours in advance to get good seats.
Two other events we suggest are Opening Ceremonies and the Music Video Contest. These are also very heavily attended events, and are always fun to watch. For those who like music, there is a dance on Saturday night featuring dance, anime, and techno music. Our Guests of Honor also have panels where you can ask them questions and learn about what they do. Many of them also have one or two autograph sessions.
