Large signposts point where to go to start the tour on the High Street. They are hard NOT to spot. The tours start and end from the giftshop (where else). Adult tickets are £7.50 (£6.50 concessions). At the start of the tour, myself and about 15 other people were gathered at the top of the stairs. When the guide asked if anoyone had a particular nervous disposition, heart trouble, etc., I thought I was going to be in for a good time.
The tours are led by guides who take on characters of the people who once lived there. I was led around by Jonet Nimmo, 'Mary Kings Daughter' in period dress.
However, the effects were too overdone. In attempting to give an example of how it would have looked, it really just killed the experience. With electric lighting, wooden floors, light projections of figures on the walls, taped sounds, etc. it seemed to lose its historical significance. I felt like a guided tour was not needed -- there is no complex of chambers, so once you reach the end of the close you cannot go anywhere else, and it meant I didn't have time to look at things in more detail. The buildings are apparently original, and I would have liked time to look at those in more detail and how the close was laid out. However, you could only go into the reconstructed rooms. These were a cattle pen, wealthy person's living room, plague victim's bedroom, etc. At one point, the tour group sat on wooden boxes to listen to a tape recording of life during the plague. In addition, the rooms in those days were very small, and still far too small to fit a large group of people in comfortably. In some rooms, I didn't even get to enter.
It had some redeming points. The last part of the tour took us into a room that has been left alone -- to me this gave far more information than the reconstructed ones. In the corner, there was a large pile of toys, left for the ghost of a little girl who is said to be said. I didn't leave a toy, but I have heard that they are given to a local childrens charity on a regular basis. I also learnt some other interesting titbits -- like whatever the popular history books and guides on other tours tell you, the citizens were NOT bricked up alive during the times of the great plague. Finally, about 45 minutes after leaving the gift shop, I emerged back there. I would recommend this tour -- if you want to see Mary Kings Close you can only see it on a guided tour, and it's interesting enough and entertaining, but if you haven't the time/money to do all of the guided tours, I would recommend the ghosthunters walks or City of the dead tour instead.
