If he has any interest in architecture he'll love it. There is a visitors center where you decide what areas you wish to visit because its a 600 acre complex not just one house. If the person has only time for one thing do Wright's home Taliesin, not the Hillside School. Although all of it is very interesting. If this person is a golfer then I would suggest bringing clubs and playing the 1969+/- Robert Trent Jones designed golf course nearby. All is about 50 minutes west of Madison, Wisconsin.
