I've only gone to some in recent times, most notably, London, MCM and Vwrop Con. Needless to say that I had a blast in all 3 events. It's so enlightening to see cosplayers and their craftsmanship and attention to detail, most people that I've interacted with are lovely and thoughtful, some being pretty adorable, and the celebrities that I planned to see are absolutely lovely and humble people. Sophie Aldred, Sylvester McCoy, Paul McGann, Katy Manning, all lovely people. Also conventions seem to be the only form of place that I can get whatever I want to.
