There's all that and more. The Centre is constantly changing (so much so that I have almost been caught out while taking a tour as I haven't realised that a car has been shifted etc, can make for a few interesting moments )
I can't tell you what you will see on your trip but be assured, you will see things that the general public don't get to.
BTW, for anyone interested. The guy in the pic on that web page standing at the reception desk in the blue FTR polo is Alex, the one who helped me come up with the questions for the last competition. Blame him for most of the hard ones.
