You best make sure to tell everyone to bring setups Allan, as last time you didn't have enough room for all of them so some people might not bring theirs this time.
And yeah, pools take awhile, but he's right. IF you can hold everyone actually there, they can run just as quickly. But people are not attentive, especially at large events, so pools take forever. Starting at 2 isn't helping time constraints either.
But at the same time I totally agree. For the entry fee, pools would be optimal.
Just lay down the law about "no show for pools, in two minutes you're DQ'd. Tell someone where you're going or face getting DQ'd." and group TVs in 2-3 sets for each pool. That's ASSUMING we have more floorspace.
