We travelled there and back by train and Jeremy and Gabrielle remained at home as they were both working.
It takes around 5 and a half hours by direct train to the nearest station to Grandmas then a 25 min drive to her house.
The children were extremely well behaved for the journeys both there and back. Mostly due to electronic devices (of entertainment, not torture)!
The trip was cut short by a day because of forecast snow, which did begin the night we left so it's a good job we travelled back when we did!
