I kept this that someone posted a while back. No idea how safe it is, but it depends how keen you are to try it. I've been planning to try it myself one day, when I don't have to deal with a small child and a pushchair at the same time, but I'll bow to other peoples far superior knowledge, if they deem it unsafe.
"Walk to PO/DL from OKW - it's sort of an "adventure" path!!
Start near building 17 and walk thru the employee parking lot...they let you walk thru..then cross over Community drive...you will see a large open area..a wide path used for storage of large trucks & equipment..just walk straight thru it towards Port Orleans..It leads right to the PO parking lot....from there you walk right into PO...from there , its easy to walk to DL...
There are no lights so make sure you are heading back before dark so you don't encounter any critters..also, its not paved so it might be a bit damp or muddy depending on the recent weather..but the walk takes only about 7 mins. We have taken our OKW rental bikes that way several times and it is a nice bike ride over to Dixie Landings...
Its probaly not an 'official" walkway..but we have encountered other people using that path and even security people on the PO side and no one ever said anything negative...its safer than walking to PO along the main roadway which is dangerous with the vehicle traffic."
