FanForce will have its annual European meet there that week also, and there will be a large Fan Party on one of the nights. The opportunity for meeting other fans from all over the world is at least as important for me as the CE event itself. I have also been wanting to visit London again anyway.
I will be in costume at least half the time, some times standing in the Rebel Legion booth.
I will remember to wear my "Darth Lars" or "Marcia Lucas Fan Club" T-shirts when not in costume.
