I don't want to panic people in to getting there early. He didn't say anything about long queues or anything just suggsted I might want to get there a bit earlier than that. Not that I mind getting there early, more opportunity to gaze in wonder!!!
Just spoke to them as my ticket didn't turn up & they advised me to get there early if you need to pick up a ticket. I said my train got in at 1836 but he suggested that wasn't early enough. Not sure if anyone is in the same boat but I thought it might be worth mentioning.
