Basically we live a long distance from both of our families and to fit seeing both in we need to travel Bristol - Truro on Christmas Eve. To get an earlier train would be more awkward in terms of timing and costs about £70 more too, but the last train of the day works better for us and is cheaper. Am fine with it being packed, rowdy, total lack of seats and chaos etc but am I being ridiculous to consider travelling that late on Christmas Eve? Have never done it before - are we likely to have the train cancelled or a bus replacement or something?
