I'm trying to book tickets for a 5 hour journey with a 4 year old and a baby- would you book 2 seats (one for 4yo and one for me) or just the adult seat and hope to find another spare seat for dd? Train company will reserve a seat for her but say if ticket collector asks her to move if train gets busy then she will have to (could be tricky when I have baby on my lap). THe only way to guarantee a seat for her is to buy a child ticket.
Should I risk not buying one? It's an extra £50ish.
