No it isn't
Not if the ticket is associated with the "major" Newport Mansions (Breakers, Marble House, etc). Rough Point is its own organization, and costs $25. I will say that if you are at all interested in the Doris Duke story, it is an interesting tour and worth the visit! The stories I heard from the guide inspired me to read 3 books on the Dukes and Doris Duke.
However, it’s worth seeing. I went last night for a “open house” type of event, so no admission fee. I totally enjoyed it. Doris Duke was an interesting woman. Learning so much about her life left me intrigued.
