No, no, no...... That isn what you should do!
The North doesn like to be treated like that! It needs to be treasured, fondled, kissed, and not with a fleeting little kiss of two nights!
So how is this:
Enter at Phalaborwa gate, and spend your night(s) at Olifants.
Then, anticipation rising, make your way to Shingwedzi, but not over the tarroad. Well, not entirely.
Early morning, head a little south, to the low water bridge at Balule. From there take the S91 to the tar, that will give you a chance of leopard.
Then move along all the way, over tar, the North is waiting for you!, to the Tropic of Capricorn. That is where the heavenly North starts.
Now that the Tropic of Capricorn loop, so you can watch Eland, Roan, tons of birds, etc, and head up the S50. Nearing Shingwedzi you will hit Kanniedood. The first part of the road there can be less interesting, but is is nice and quiet, beautifull, and getting better the further north you go.
Spend a night at Shingwedzi, 2 really, and enjoy Kanniedood and Red Rocks loop.
And then hit the road for Punda. I am not sure about your budget, but if you can afford it there is no real option really, the tents! That is where the leopard walks (you can see her from the hide too), the genets and the bushbabies visit you on the terrace, and where you will find total rest and relaxation. Just watch the braai, you will have to walk a bit to retrieve your meat if you drop it.

And then get up really early, and head off to Pafuri picnic spot. Say hello to Frank from me, and do some birding with him.
The rest is up to you, but Punda? 3 nights.
On the way back you may want to sleep at Mopani.
Oh.... I did not leave you time for the south?
