The pathway begins behind building 55 at OKW. It is paved the entire way and lighted about 2/3 of the way. (I wouldn't suggest late night strolls over this route.) A stroller shouldn't be a problem over the walkway at all.
Caskbill has prepared a detailed report of the route, including photos in this <a href="http://disboards.com/showthread.php?s=&threadid=39529">Pathways Revealed</a> thread.
Enjoy!
