Not sure what to write here, as I feel a bit of 'professional' tact might be required.
I've been too both the NEC one and the Excel one as a punter, with a view to possibly doing it for the business. I came to the conclusion that it wouldn't be worth the cost. At least, not at the moment. Make of that what you like.
The organisers are trying very hard to find a formula that works, but as yet, I don't think they've found it.
If you're local to it, perhaps pop along. But I wouldn't drive to the NEC from Bournemouth for it.
It's a shame, as I think a great golf exhibition would be awesome.
