Well I'm planning to go with a mate and cousin and will play it all by ear - I've been before in a car (not a Cali) and always found accommodation. Prices for campsites and hotels are hiked horrendously close to the stadium, but we always liked to get out of town or off the beaten track a little and have never been disappointed, although it's worth making sure you can bus, train, taxi in so you can enjoy the hospitality. I'd stay away from the England Supporters recommended sites as they are a bit raucous, unless you like that. Never had any trouble - seen a bit though - and its obvious that there are some places you just walk past and don't go into. Met some great friendly people from all across Europe (2000, 2004, 2005 Confed Cup) and the world (2006) and fanfests are brilliant for the atmosphere even if your team isn't playing. We've always managed to pick up tickets on the street but I think that'll be impossible this year as security will be through the roof - still worth going. The overnights getting there & back in obscure little towns and villages meeting the locals is just great. All good fun, we just needed to exercise some vigilance and common sense to stay safe.
