Lets say, an aircraft that would hold the wife and 2 kids + luggage?
"Luggage" suggests that you think a PPL is actually useful for travelling, with the ability to turn up at a particular place at a particular time, like wot the airlines do.
Dunno what the weather is like round your way, but here in the UK a plain vanilla PPL is essentially not very useful for such a purpose, as most of your planned flights will be cancelled for weather reasons.
See many previous threads on this topic - basically to increase the chances that you personally will be able to take off you are likely to need some instrument qualification on top of the basic PPL, and to increase the chances that the aircraft will be able to take off you need IFR instrumentation and, for the UK in winter (as I said, I don't know what your weather is like), a de-icing capability.
