I find it ironic that they have teamed up with Stuff magazine to give tickets away. I went last year and it was mainly for adults with young kids. Anything being given away was biased towards little kids, although looking at the bags it was cack like 1GB USB sticks and a drink! Most of what you could buy was cheaper elsewhere on the day, I bought the odd things from Amazon that I was interested in. Just bought a Bluetooth selfie stick for a fiver. A lot of the stalls seemed to sell the same Chinese generic stuff with their own labels stuck on it. and yes we did go in the super theatre, and again it was a little interesting but aimed at kids and advertising company products. I personally would not go again even with my kid when he's grown up a bit more, probably take him to a Curry's store and show the same sort of things without the fuss.
I took a day off last year to take my son as it fell in the school holidays also. It was ok for a day out. I live in Nottm so drove and parked for £12. Took a packed lunch as I just didn't know the setup of food anyway. We got there for opening at and I was back home for 2:30 I think. My son was 5 years old so he just wanted to go on the consoles to play but with adults and teenagers not giving him a look in he had no chance. I had a go on that MG Rover driving track but the best thing for both of us (and has created an impression on him) was the Robot Wars. He sat there for an hour or so mesmerised and has since been loving the repeats on Challenge etc. Just a shame they said we have an hour break and then we will be back. If we had not done the trade fair before (as that is what it is) then we would have killed time and gone back. Free if you are fairly local then it was ok. Would never pay for it and not worth travelling more than an hour or so for.
enjoyed it last year, will get the tickets for the show too as that was fun...hopefully get some decent free stuff instead of a crappy ebuyer tshirt and a phone stand this year though :)
