In defence of the Motorpoint, I think the problems arise from World Snooker having not quite fine-tuned the best way to host a flat 128 structure yet.
As I said in the Welsh Open discussion, I went up for the semis and the final, so was only at the one-table set up. It was chronic. They'd essentially divided the venue into a quarter of it's size. Meaning, that a venue that was advertising Michael McIntyre comedy gigs, a Katherine Jenkins concert, Disney on Ice and some WWE Wrestling, was struggling to hold 1000 people. It was obvious it could hold more than people than were there, but because they had to scale down the size of the venue for the sake of their only being one table, they had basically the venue too small to be used very well.
But, considering 128 players start at the beginning, and the tournament is only a week long, World Snooker is going to struggle at one end of the tournament or another. Either it's cramped at the start of the week, or it's size becomes problematic towards the end.
The trick is going to be to find a venue that is suitable for the entire tournament.
