Irish Border Control. True story I had been in Europe and only had 10 days left on my EU visa. At the time you couldn't extend. Flew into Dublin Passport control started asking questions like; how much money do you have physically on you (about 35 euros) Where are you staying (haven't booked) what are your plans? That is very vague. Are you here to work? Even to me it didn't sound good. I could see the interviewing woman was grappling to understand me. Once we sorted the money thing she said "Are you just here for a good time" YES! YES! that's it. 3 month EU stamp. Ireland should have a line called People here for the Craic
Last time I flew into a place without accommodation booked.
