I'm travelling between Watford jnc and Windsor, on 5th August. 2 adults 3 children. 14,13 and 8. Do I get a straight single with my family railcard, £28.45 is cheapest or is there any other ticket we could get. Also on the Friday were travelling into london. Doing sightseeing so travelling from Windsor into London around 9am.. Only going around zones 1-2, so any idea on best value ticket please. Any help/advice most welcome. Thanks in advance. The ticket on Friday from Windsor into London is a single journey, as we have tickets back home from Euston in the evening.
