There's two of us off to Wolfsburg in September, possibly taking in the ring on the way back. Takes a fair bit of planning mind, but it's perfectly doable. In terms of distance, the shortest route is Dublin - Merseyside by ferry, Merseyside - Hull by road, Hull - Rotterdam by ferry, drive from Rotterdam. There's a distance penalty to go via Cherbourg but then only one ferry, that is if the French dockers let you off the boat
