Taking dd (6) to London from Newquay in about 3 weeks and wanted to use the sleeper train to save on a hotel and cut out the journey, lol, but all the berths are booked. We could book normal seats and go but I have paranoid ideas that someone might run off with our luggage or dd in the night but it would be a lot cheaper and quicker than going in the day and staying an extra night, but obviously would rather do that than take a stupid risk.
WWYD - am I being madly paranoid or reasonable?
