I completed my trainign at East Midlands, and after starting it at Glenrothers (v. small) it was a bit of a culture shock!
However, i would say that it is excellent to learn to/ fly into/outoff a large airport.
If you use East Mids always request taxi to one of the two clubs (DONAIR/ East Mids Flying School) which are away from the main area and at least one of them provides free coffee.
Avoid peak times (8am/4-5:30pm) otherwise you could find yourself holding over the cooling towers at Kegworth for 30mins.
Lots of people learn to fly there so its no supprise to share the circuit with other C150/PA28 types.
Plus, I have always found Air Traffic to be great (some are instructors at the clubs), so dont be afraid to ask for any help/ab normal requests.
