No way Kiwitea holds more than 1000 people - the facilities (all three toilet bowls!) wouldn't have a chance of handling it.
Also to the contrary regarding QBE, yes the pitch sucks but it is a much better 'arena' and much easier to get to and park at than Eden Park or Trusts.
No it's not. Eden park's got the best transport links for stadiums in Auckland. There's a train station next door, regular bus services to Kingsland, along Sandringham/Dominion Rd, if you don't park inside, people hire out their driveways or there are plenty of side streets to park on. Shark, even the airport bus stops close by (Dom Rd).
I went to all U20 WC games at QBE, there was no parking at the stadium, parking was at the uni or further away, buses were only from town and the northern clogged up because it couldn't handle the extra people. It took 2hrs instead of 30-45mins to get home.
