Okay... sooo... We'll be in London, then up to Scotland for a few days, then fly to Dublin for a few days. We were going to fly back to London where we'd stay put for a week and then take a day trip to Paris via Eurostar.
However, someone on TA suggested we fly to Paris from Dublin to Paris, stay the night and then Eurostar back to London. Actually sounds like a good idea!
So went to the Eurostar web site and played with the journey planner, and I don't know if I'm doing something wrong, but it looks like it's significantly more expensive to go one way from Paris to London than do the round trip! I tried a few different dates, and it still comes up more expensive. Am I doing something wrong, or do they not like one way travellers?
