Hi, I am planning a trip to explore the sights and Christmas lights with my husband, 9 year old and oap mother-in-law on the 21st December. I have seen that Park Royal ticket office is closed on the weekends and had planned on getting day travelcards on the day. I know I can preorder them on the website but they don't have the off peak zone 1-4 cards available and would rather not pay the postage charge!! My question is - is there a ticket machine at this station? I am assuming there is but the M-i-L is a worrier and has never travelled by tube before - this is just one more thing for her to fret about!!
