Have heard that they don't have a regular walkaround appearance by Captain Jack for just this reason. It was attempted at
Disneyland and is no longer done because of grown women getting too enthusiastic the performers who played him.
I believe he's available on a limited basis at some of the special parties and on the cruise. But you won't find him out and around the park. He does do the pirate tutorial, but there's apparently a reason why he runs like heck out of there when the show is over.
