I think people are being a bit unfair here and looking at the headline prices. If you consider that for children under 16 the ticket will be priced at their age and that the road-based events are free to watch as just two examples then there has obviously been a lot of thought gone into trying to make the games accessible.
The other side to this is of course the premium seat prices, which are undoubtedly pretty eye-watering. However, why should such seats or events be priced cheaply when some people will attempt to profit from them and make money for themselves? At least this way the games are clawing back
some of the investment, and personally if I was going to be paying a high price for a seat then I would prefer it was to the organisers and not some scummy tout.

I think the games will be well attended, partly because the audience base is Europe-wide and the transport links are there for people to come from far and wide, and partly because you can't compare London 2012 to the utter shambles that was Delhi. I've got experience of both and the organisation for the Olympics is light-years ahead.
