Holloway, if you are flying from Manston then there is no way you can get lost because you have a coastline to follow!
I bet that you will always be able to see the coast during your training and if you can see that, then you will always be able to find your base. Go to the coast & turn left or right as appropriate - forget the power station its not as obvious as a coastline.
I learnt at Southend so I am speaking from experience.
