Gonzo,
It is unfortunate... when I did my 15 hours worth of flying 'training' with NATS, I ended up spending a good part of the time teaching my instructor (who could fly the aircraft very well), the finer points of VFR navigation planning and execution.
Thought I'd almost got there until on a trip to Prestwick, he couldn't find the airfield despite the humungus big line feature that leads you all the way in being in front of him for several miles without him noticing... and he wasn't even flying, he was purely navving while I sat behind and another student flew
Back to the thread... the olympics will be fine... As for the post a few above talking about the departures being possibly the worst... I'm sure even the minor aerodromes will be regulated by some pretty stiff slots
