The boat from OKW to DD stops at SSR in each direction. It is about a 20 minute trip plus stops. The boat from OKW runs on the hour beginning at 11:00am until 4:30pm. At that time it runs on the hour and 1/2 hour until 11:00pm. (It stops at SSR on each leg of the trip). PO has it's onw boat and a different schedule. It does not stop at OKW or SSR.
There is fishing at OKW along the canal. Fishing is catch-and-release. There are also fishing excursions available thru Disney tours along the canal and in the DD lake.
Enjoy!
