After the trip to the centre yesterday I have to say it's actually a bit smaller than I had thought. They probably concentrated on building a greater number of courts, rather than create more room for people to move around. I'm not sure what the official "measurements" are, but size-wise, it's nothing compared to Sydney, and even Adelaide. If anyone plans to get practice photos you'll be disappointed because there's no space for spectators in between most of the practice courts, so you can only see them behind a fence!
Also, everything seems to be cramped, and on one side it's directly looking at a power station! They really should've made more space for what they're trying to build. The centre court itself is good, you can probably get a good view even from the back rows.
That aside I didn't stay long but saw Gasquet practicising with Stepanek on centre court, also Nieminen with Melzer outside. (Heaps more women were practicising, except for Hantchuhova and Safarova I didn't know who the rest of them were!)
