My parents want to have our children to stay in the summer holidays and we are trying to work out logistics of getting them there & back. By far the easiest & cheapest option is putting them on a train at London and my parents meeting them the other end (& vice versa for the return) but I'm not sure if they're a bit young to do a big journey on their own. Eldest regularly travels by bus on his own and youngest has walks himself to school/local shops but it's obviously a big jump dispatching them off 200 miles!
Any thoughts?
