Teehee I almost thought of going... checked it out. Entry to the convention is 22 GBP, but that just gives you right of entry, and then you're at a horror convention where you can buy all sorts of horror parafernalia. If you want to take part in the meet & greet, in the Q&A or get a signature, you will have to pay extra.
I don't do horror. Of all the special guests I only knew Meat Loaf.
Tim is wheelchair-bound since his stroke, he has paralysis on the left side. He won't be signing at the event due to this, but you can leave your item on the table and it will be returned to you. There'd better not be anything happening to my GK3 box!
Anyway, weighed a lot of pros and cons - and decided not to go for it. I may kick myself for it later, but due to the current circumstances...
