I know that vendors rate this event very differently but for me, this con has always been amazing. It is super affordable for artist alley tables, especially for the Summer event where you have 3 full days to trade. It is a bit of a hit and miss where you get placed, but I have been lucky almost every time and I love how busy it is and how many nice vendors and attendees I meet. London hotels are expensive obviously and for me, who has to fly to London that adds onto things too, but the event itself has been great every single time for me, especially the Summer edition. The food avail at the venue is expensive but really really nice! And they have excellent coffee. Wish US cons were as affordable as UK cons!
