The art museum is pretty nice; the carriage and car museum is cool; and it's neat to walk through the greenhouse.  Those are free.  However, nothing really separates the $12 house tour from other house tours.  Like the other ones, the docents don't focus on anything interesting, like history or the architecture or the building itself.  They focus on some family story that may only be of passing interest because the family is rich.  Kind of like hearing about Paris Hilton or the Kardashians.  B-o-r-i-n-g. And what kind of tourist attraction doesn't allow pictures?
