Wow! What an amazing historical interesting place to visit. Viewing the house itself if 5 stars easy. The only reason I gave it 4 is there is not much organization when it comes to touring. The two tour guides didn't know which one was supposed to take our tour and neither really wanted to with both suggesting the other gives better tours and should do it. Nice tactic but I didn't want to listen to it. The house itself if fascinating and the stories as well are great. I didn't know much about Frank Lloyd Wright but learned enough this trip to make me very interested in learning more and visiting more sights.
They are currently trying to get permits to get the home historical preservation status and build a gift shop/museum underground as well as an amphitheater to host musical events. I booked on the foundation website but some of the people in the group appear to have booked somewhere else.
Beautiful home, beautiful view, and well worth an hour of your time to go see.
