I've left it a bit late to book a bike space on the last train back now - can't get out to the station tonight for childcare reasons, and it'd be pushing it a bit to get it sorted at the station tomorrow on my way out, even if the York EC staff do seem to be reasonably clueful!
I'm happy to do whatever, but my sensible train options are the 22:03 from Darlo or the 22:30 (which leaves a minute or 2 early!) from NTR. Maybe we should plan slightly more ahead for a Darlo run one week, then I could even be organised and get cheap tickets!
