Bases chosen for first 20 participants

One of the dumbest decision in 2012 was to award the European championship (special edition) in 12 cities across the continent this summer. Four teams are yet to qualify for the event at the end of next month, while the first 20 participants who are in the finals have already decided where their camp will be situated.
Last Monday it was the final deadline of giving the list, and most teams (like it or not) are going to travel back-and-forth during the group stages. Those who are 'hosts' at home will stay there, but those who are nowhere near it have picked the nearest countries / cities or in between. All twenty bases with their names are available at the website of the organization.
