I can see why people say its best in a quiet one and why its best to learn in the thick of everything else. its the deep end as opposed to a slightly deeper end
I think what ill have to do is go and have a poke around, like you say on a weeked. Im quite lucky in that respect though. I work shifts ( at BHX ) so i am able to do weekday flying which ive been told is often better and also sometimes cheaper since their less busy student wise.
