We were thinking of going by 2AC – for more comfort. We got one seat among four of us in 3AC. Realize the importance of a full seat while travelling. In the night three and later ALL four of us slept in one seat – I was only thinking about how we take things comfort for granted – We are very few of the lucky in the world who have the luxury of comfort. We choose to travel by train to get all us get used to of discomfort. And this time it was really tough – but it was amazing how kids did not for a single moment complained about the space.
