Thanks paperclip810, wonder if you can help me a bit more. How do you know which bus to get? Is it the only one there? And does it drop you off at CTC or is there a short walk from the stop?
Also, in response to your post a couple days ago about it maybe being worth getting a work experience at an airport if you are an aviation novice, i second that idea. I spent 5 days at Edinburgh in April this year which i organised myself having been for a more unofficial visit in 2008. During that time, i spent time with the ATCOs, assistants, ops and engineers. It was all very interesting - the engineer who i spent an afternoon with was a real fountain of knowledge and he even took me out and showed me the radar and other navigational equipment around the airport as well as explaining the new technology they'll be receiving in the near future.
With ops, i spent most of my time racing down taxiways in a jeep that was squawking like five different types of bird to scare the real ones away! However i also got to go to the operations room and see everything ops do around the airfield.
With the ATCOs, they were all very friendly and answered all the questions i had as well as sharing extra pieces of information with me as well. If you want to try and understand a bit more about the rules and regulations around ATC and UK airspace, a visit to an operational unit to see the radar used and how it's used is definitely worthwhile.
