If you work for the emergency services, you will receive completely free entry to the Blackpool Tower. Just ask on the door. I went on 15/09/09 and asked if they did emergency services discount. To my surprise it wasn't a discount, it was completely free. They will require you to show your ID and they will print your tickets off, allowing entry to the circus and the tower. I went with my partner and we were both given tickets. I'm not sure how many tickets you will get. I doubt if you turn up with a coach load that you will all get free entry.
