We've been to Mount Vernon twice. Once, as a family, and the second time to show our relatives that were visiting from out of town. I think this is a historical site that you can keep going back to see and still learn something new. The grounds are absolutely beautiful, and the house is spectacular with it's appearance still as it was in the 1700's. As you tour the home you will have guides that will tell you different stories as you enter each room. These tales are very educational, as well as interesting. After the home tour, you can freely roam the grounds and visit the outside facilities and gardens. I think you can pay extra to get a personal tour of the grounds, but we chose to do it on our own. It is truly amazing to see how people lived in colonial times. Make sure you go on a relatively cool day, for Washington weather is brutal in the summer time. There are some steep hills to climb, so be prepared for a struggle with baby strollers. Strollers are also not allowed into the home.
