I got a chance to visit the Washington Nationals park after a day of meetings in 2016. If I remember correctly, the park was within walking distance of the tourist/hotel area, but it was a bit of a hike. Nice park and a very open park with only a few seats in the straight away outfield, where they have some indoor club seats. I think this is one of those stadiums where you are not allowed to walk around the whole park and I am not a fan of that design. Anyway, got my pole-to-pole pano from a seat down the third base line.
