Our favorite part was the gardens--they are beautifully maintained. The Grand Allee is stunning! The tour of the house is limited to the first floor only, but the volunteer docent was knowledgeable and personable. He let us know that the house will be closing soon for some updates, so you may wish to check before heading out to see it. The actual museum was meticulously maintained, and took us about a half hour to walk through.
The cafe was reasonably priced and good, and has soups, sandwiches, salads, and teas.
We don't have kids, but in my estimation, this would be a little bit boring for younger children. Older kids would do fine, and anyone interested in history, art, and/or gardening will have a wonderful experience.
