I agree.
I'll tell you what, I'm on the Point A to Point B thread and I said to DH, if I was relying on Disney transport I would not make ADRs at a resort not in my direct vicinity (monorail or Boardwalk). What a pain to "transfer here," "park still open then..." etc. If you have a car, you will use it to get from resort to resort for sure.
And OKW to MK resorts is so easy. You could drive there and back a few times, I'm sure, before the bus gets all the way around OKW and to MK and then you transfer (see, that word) to monorail or boat....
I think it took me longer to type this post than it will to drive from OKW to Poly.
Enjoy!
