We have been invited go a very good long terms friends babies christening soon, it would be a three hour journey each way (on 3 trains) so 6 hours travel on the day, we would be able to be there for around 3 hours. I have a 1.5 and 5 year old and I just don’t know if it’s an ok idea to travel this distance in a day, we can’t go up the day before and would have to come back the same day so staying over to break the journey up isn’t an option. It is a close friend who we haven’t been able to see for some time due to the distance. Any opinions on what may be best to do? Is it unreasonable to travel this much on trains for lo’s in a day?
