We did the walking tour, you really do walk, bring water and wear comfortable shoes. Tour was fascinating, We had two guides and Wendy especially was excellent. Guides mingled and talked with us also. No we didn't see anything supernatural on tour, but didn't expect to. Later we walked into the Menger bar and hotel, and it started to smell really strange to me, I had to leave. But during the tour you do not go into buildings, there is plenty to see. Sisters Grimm gift shop is interesting also.
