To be fair the travelling times between London Paris Amsterdam Milan and Munich wont be that dissimilar to that of polish public transport, and probably far easier than Ukrainian. It took me over 5 hours to get from Krakow to Lviv, an equivalent journey in western Europe would have taken no more than 2 hours.
I still think its a bad idea but travelling from one city to another wont be that bad, unless they chuck in Moscow
But one of the main contributing factors to such low travelling fan numbers during Euro 2012 was the logistical nightmare. Long distances and a choice between extortionate air fares, or laborious train/road journeys put huge swathes of usual fans off.
So, what have the illustrious powerbrokers decided to remedy this? Make it even more widespread. It beggars belief. At least when travelling between Donetsk and Kyiv, for example, fans could stop-off en route and be in a town or city that, too, was embracing the Euro 2012 party, even if it wasn't a host city (many cities out here in Ukraine had Fan Zones even if they weren't a host city). So, you could stop off in Poltava or Dnipropetrovsk, stay the night to break your journey up, and mingle with other nations' fans in the fan zones whilst watching games of giant screens. I just don't see that being the case in this proposed format, as it'll be spread too far and wide.
And as for Moscow - I'd bet a month's salary that they'll be included.
