Karen helped organize our morning starting at 8:30 til noon. Our gro u p size grew as the date got closer and she was great with the additions. She also helped with the couple of guests that couldn't walk far and made sure all could hear the tour guide. When our bus pulled up in the pouring rain,she had rain ponchos in hand! Karen was the best!! This place can be toured over and over. Everyone , all ages loved it.
