I'm planning a trip to Ireland with my business partner in March and am looking for transportation from there to Amsterdam via the UK.. is flying the only way? If driving / busing / boating is possible what sort of trip length are we talking.. hours? days? Looking at maps the entire countries don't look much larger than 1-2 US States, but seeing as how I've never been to Europe I thought I'd ask people who have

Any insight is greatly appreciated.
