I wonder if that is what we encountered? Nothing like 3 hours, though, thankfully.
So true. [Especially problematic if you're trying to get from one flight to the other, and you miss the sign saying "go that way" (to the left) so you go through where you think you're going through (to the right, through a security area), get sent aside because they think you have two 311 baggies (which you do, but there are TWO travelers), then ask for assistance. And are told to go to the right down that hall, go out the door and turn right, and at the next hall turn right (at this point I'm thinking "hey wait a minute")...and you do that and the clump of people who were in front of the "go that way" sign are gone and you see you messed up. But at least the security guy was kind about it!]
Oh yes. That's the adventure part. Vs the flying in at the last minute part. Heck, you're over there, take some time! And you can gamble on the ferry (slot machine type of things). And drink. The scenery was incredible. And on the train the lady with the cart came by saying "here's your trolley", which was just so adorable-sounding to my ears and I loved it. I definitely got tea from her. Hard to take time from Ireland (which is why you're wanting to fly in the day of, no doubt), but if you have wiggle room in your schedule, it's a lovely way to travel to where you're going. This all-Irish-descent girl liked the UK a heckofa lot more than she expected.
