first go around the resort - then take the Turtle pond route to West DD - MP - then around SSR then back - not sure how long - I would say at least 5 miles? might be less.
There are great routes that go from OKW to SSR through DTD. These are my husband's favorite long routes. Just two weeks ago, he started at OKW, did the entire resort, hopped over the paths to DTD, did DTD and over to SSR and back to OKW. I think he did it twice for about 16 miles.
