I've actually been here several times. Three times as a sighted person with family. And most recently as a blind guest with my girlfriend. And I'm just now getting around to reviewing it! First, the entrance to the site from Route One has changed. Don't rely on your navigation system unless it's been VERY recently updated. Follow the new signs to the new Woodlawn Road entrance. It's further South, at the new stop light, just before Fort Belvoir. There's plenty of parking in the graveled parking lot, including several spots for handicapped visitors. The parking lot is between the two attractions, so go to the main mansion house FIRST to purchase tickets for both sites. The main mansion house at the Woodlawn Plantation is an ORIGINAL building from the period right after George Washington's death. There's a little bit of furniture in it right now, but it does include some period pieces that are very interesting. The main mansion house is here as an architectural example of the period. And as an example of how people lived during that period. The docents are very good at imparting an idea of what life was like during that period. You enter the main mansion house at the driveway in the "back," and start in the gift shop where tickets are purchased. The tour winds through the house, and returns you to the gift shop area. There are bathroom facilities available, but you have to go around the outside of the house, down some stairs, and they are in the basement. Very clean and modern bathrooms. For the blind/visually impaired traveler, there are MANY stairs in this building, and you will have to go up and down them during the tour. No way to avoid them, and there's no elevator. Be prepared. Be careful, as not all the steps are of the same height. There are handrails. The house is very open, with roped off areas. You will need assistance to help you get through some parts. This is a historic building in every way. The Frank Lloyd Wright house is a short walk from the main mansion house, and it's across the graveled parking lot, on the other side from the main mansion house. You go down the curved paved driveway to the house and wait for a docent to gather up your group for a tour. You can take photos of the outside after the tour. It's very tight inside, so groups are usually pretty small. Very good example of Frank's Usonian Style house. For the blind/visually impaired traveler, there are steps in this house too, but not nearly as many. NO handrails. The hallways are tight, but that means you can put out a hand and "shoreline" along the walls through much of this house. No roped off areas in this house. You should be just fine here on your own. Good way to spend a couple of hours if you're interested in history and architecture. Highly recommended.
