Hi Maza, I've been a few times and the viewing is pretty good. There are 8 courts in total, with 4 on each side of a raised walkway. All viewing is from this walkway or an adjacent viewing area next to court 1.

The photo in the link is of one of the courts taken from the walkway. The good thing about it is that you can see all the courts at the same time. All of the viewing is from above, none of it court level.

Also, here's a link to a video clip. You can see how close the other courts are, which can be a problem sometimes with stray balls etc.
