I reserved passage on the ferry from Dublin to Holyhead in Wales no prob, now I am trying to get a train ticket to London tomorrow night, and the UK train system SUCKS! To buy a ticket online you must have a UK billing address (I put in the post code for Buckingham Palace just to see, but of course that's not where my visa bill goes), or use a "fast ticket" machine, of which there are of course none in Holyhead station, where I will be attempting to embark from.
So basically I'll be arriving in Holyhead at midnight tomorrow night with no passage out, hoping to get a ticket somewhere farther south.
Fuckety fuck fuck.
