My wife and I took the historical tour that left the main square at 2 PM and took approximately 2.5 hours for 7 euro. Our tour guide "Hannah" was very good and well informed. She truly earned her $7 euro and went above and beyond for us and just one other couple. I'll have to admit that towards the end we had had enough because she almost provided too much info and was hard to keep it all straight. Also she was a little difficult to understand at times. I would highly recommend the tour if you are at all interested in German history.
The Nightwatchman tour was also $7 euro and we were on the tour with close to 100 other people. So $700 euro for an hour of his comedic history is not a bad way to make a living. This was more entertainment mixed with some history. Also as other people mentioned he gave the kids pulling on his cape and running around his feet a few chances to calm dowm before he said "knock it off kids". That just added to the humor. I would also highly recommend this tour because it was just plain fun.
You can easily see this beautiful little town in a day but do yourself a favor and avoid Saturday and Sunday. We were there for the Christmas market which was average at best. Friday was nice but Saturday was horribly packed with people.
