Not directly - but she can take two boats. OKW to the dock at DS. Then DS over to SS. It would be a pretty simple trip. Unless she takes a cab or Uber, she'll need to transfer to get there (2 boats or 2 buses). The boats would be much easier, and quite peaceful - a nice way to prep for a spa visit!
She could take the boat for OKW to DS, and then walk to SS, but it's not a short walk from the dock.
