This is the location where Lincoln spent the night in Gettysburg before giving the Gettysburg address. It was informative and somewhat interactive. Main point of interest is the bed where Lincoln slept. Not sure what else they could have included - maybe an actual person giving the history, rather than signage. If you want to see the room where Lincoln slept, I recommend going.
