Very worth it, but it takes a long time. Lots of standing and reading. We didn’t take the audio tour, and I sort of regret it. You not only see the Lorraine Motel, but also the boarding house where James Earl Ray allegedly shot from. The tour has two parts. First you walk through the building attached to the Lorraine and then through a tunnel to the boarding house. Cameras aren’t permitted except outdoors but there is a camera check. Very deep and moving at the parts where you see the balcony where he was assassinated. Absolutely intriguing.
