I wouldn’t make a special trip for it.I went many years ago as I had a free ticket and a very cheap train fare. Met @BrumJim for a coffee IIRC!
There’s also one at Alexandra Palace in April if London holds more appeal than Birmingham
This pretty much makes my mind up for me not to go. I had seen the London one but too early in the year for me and not quite as easy to travel to with the NEC being pretty much beside Birmingham airport. I'll just save the pennies and put it towards a bigger July trip with the family.
I might you up on that offer sometime @BrumJim
