It's not too far for me (I can drive there in half the time it takes to get to Ally Pally) and I'm intending to go Thursday or Friday - not sure yet...
I dare say that as it's the first time for this venue that there might not be as many exhibitors there - but if the turnout is good maybe more companies will go in the future.
I've decided not to go to Farnborough this year as it's the same time as Who do you think you are (and I can't afford both) and I'm giving Stamperarma a miss as it's bang in the middle of the two things I am doing - but the August one is still an option.
I am still planning to go to Ally Pally in April though, although I may change my mind.
