I am so sorry at having to post this, I know how annoying these cards are but I don't know where else I could get the info I need......in a language I understand (think explaining to a toddler!)
Hubby needs to get from Kings Cross to Baker Street on the 16th Jan and then Baker Street to Heathrow on the 17th and then Heathrow to Kings Cross on the 21st. Is he better off with an Oyster Card (I cannot for some reason fathom how these work - my brain just can't compute the endless bits of information I've read on it!) or just buying single tickets??
Again apologies for what I know is a question that gets asked frequently, I have tried to read previous posts on this but I just can't get my head round it.
