Just got back from the stadium tour. It was awesome, definitely worth a go if you can. Have to say I was one of those who was a bit sceptical about the size of the stadium, but having seen it on tv and now in the flesh, I think they've done a great job with it. Got to see the VIP lounges, the seats where Agnelli et co sit, run out of the changing rooms onto the pitch - had a tough time dragging my 3 year old away from the grass! Ticket booth opens 30 minutes before the tour starts if anyone is thinking of turning up on the day.
Also spent an arm and a leg getting the last few tickets for the Lazio game - definitely need to become premium member now... Apparently most were sold out to the premium members, all the tribuna family gone (the prices for this are great btw). The local ticket shop told me they don't bother selling juve tckets anymore as they are all sold in minutes before they get a chance to get hold of any.
