Euro 2012

[ThatsTheFootball]

was wondering if ayone has any experiece of travelling to euro or WCs and has any advice??
i've checked with travel agencies and there packages can be expensive. One has a 3 match package with match tickets guaranteed at nearly 2350euro.
another has 3 match package with every thing included expect match tickets for 1599euro.

whats the chances of getting tickets while out there? or would yoiu be better having tickets sorted before going?
