My big tip for visiting the Olympic village is to seek out NBC news broadcasting site from American.
They are the most open, most interactive with the crowd and at times the most accessible too. They have a semi-circular studio just to the right of the Velodrome + Basketball in the Olympic park, next to the pedestrian walkway.
Their very well known (super-star status) presenters were in the news recently when one of the anchor women was ousted in a multi-million$$$ deal, but that aside, they were still very engaging of the audience there, extremely pleasant and friendly and approachable, whilst putting on all kinds of entertainment between interviewing various Olympic stars and celebrities, which made for a most engaging experience.
Although it sticks in my throat to say it, much more engaging than BBC1, who were mainly screened-off behind smoked glass perched high on a pile of cargo containers!
According to various sources its a pity that their actual coverage of the games is cr#p , c'mon not broadcasting the 100m final live is not good and apparently missing the part of the opening ceremony regarding the London bombings was disgraceful . Seems to be that events without US involvement sometimes are not even shown .
Nobody beats the BBC at these Olympics - their coverage of events is amazing.
The broadcasting centre set up here for all journalists from around the world is SO vast, you can fit 4x Jumbo Jets wing-tip to wing-tip inside it!
All I'm saying is, watch the BBC on TV by all means, but an Olympic ticket for any Olympic park venue allows you to wander around the that vast area that encompasses many stadia and events being held free within it too, you may find the NBC activities interesting around mid-morning, as they prepare to broadcast live to America at breakfast time.
It's a great atmosphere even if you just get a ticket for Olympic park entry IMHO.
