Our extended family including seniors and young children toured three of the Newport Mansions. Our primary objective was to see them decorated for Christmas.
The Breakers, Marble House, and Elm House were all open for touring. Breakers included a one hour guided tour; the others were audio. Tours were well done and engaged all ages of our family members.
I had hoped to see more elaborate decorations. The central halls were well done but the remaining rooms weren't decorated much at all.
If you've already seen the houses it's not worth a second visit. If you've never been, it would be fun.
