You need a popular/famous/realy talented artist/writer/actor/etc who is known for doing furry books/movies/art/etc for your GUEST OF HONOR. Some GOH posibilities for cons have to be asked up to two years before the con and some will only do cons if paid. They must be transported to the con and given rooms,food and such. Most cons do not pay bar tabs though. Two GOHs are a good idea in case one can't make it and cancels. Having back-ups is good to. It is posible to have a con without any famous GOHs, but it tends to hurt membership a bit.
