can someone please explain what's the benefit in rushing through the PPL and get it done in mere few weeks if you don't plan to go CPL?
Hhmh. Impatience?
That was part of it for me. Your learning curve is also higher if you don't have lengthy breaks inbetween lessons, if you need a rational argument.
But apart from that: The 4 1/2 weeks I spent in Southern California training for my PPL were by far the coolest 4 1/2 consecutive weeks in my life - great fun (and hard work) and I don't want to miss it.
I'm sure everyone who chooses the slow path enjoys it very much, too.
For those interested in the PPL in the US, please DO have a look at this thread (pinned to the top of this forum):

It contains a sheer wealth of information and was the single most televant source of guidance for me in the months before I went overseas.
