I can highly recommend it as a place to visit & stay, although you should have a car with high ground clearance.
I used to drive there in a VW Golf -- the original box-shaped one, very, very slowly with one wheel in the middle of the road and the other on the side of the road to avoid for the deep ruts. On one occasion going home from the lodge on the mountain top, after perhaps a 40 minute crawl, I reached the tarred main road which has a 100kph speed limit and accelerated. My wife shouted at me to not drive so fast ... I was only doing 60!
There is another lodge in the forest which has 4 (5?) rivers to cross. My golf happily splashed across all of them except the last one on the return journey. It always hit a rock with the underside, I could never find the rock and it never hurt the car. :-)
My next car had high ground clearance and I drove the route normally at a reasonable speed, but the first salesman lost the deal because he insisted I needed a 4x4 :-) I guess he never saw the Top Gear episode where the backup car, an old VW Beetle made it right across Botswana.
