If you're thinking that a light aircraft with a PPL might be a useful means of transport, then you should be aware that for most people it isn't. For all sorts of reasons from weather through cost to airport closing times via weather and the need to stay sober at the party if you're flying home. Oh, and weather of course.
If you plan to (a) acquire some instrument flying qualification and (b) buy your own aircraft and (c) operate from somewhere that doesn't close at 7pm then you'll get a better answer.
