Am looking at going to Europe with two children alone - DH coming a few days later. The trip there involves 2 hours on first train, then a change of stations (about10 min walk away) with 1.5 hours to change trains, the another 2 hour train journey arriving at 10pm. Am I mad to attempt this with a 2 year old and 7 year old solo. With luggage and pram. Or should I pay extra in order to be able to break up the journey and stay a night to break it up? what would you do?
