Going to see the london 2012 olympics

I was planning a trip with family to go see the london 2012 olympics. I know it is still years away, but this is kind of a big trip for us so getting all out ducks in a row is not a bad thing. I am sure that the booking of hotel rooms has already begun. Flights will have to wait a while but trying to book accommodations could not hurt. We will also be planning on what to do when we are not attending the games. Sightseeing will be a big part of this trip as well. London has so much to offer.
