Letittia, I do appreciate the room guides and often speak to them because they can be funds of knowledge, I do not float through the rooms like a ghost but, generally, I expect to initiate the contact. Recently I have experienced what I can only describe as a determination of the NT to tell one story at a venue, regardless of whether it interested me or not and send me a questionnaire afterwards to ask, not whether I liked it or appreciated it, but whether I had been aware of it and understood it.
The most egregious example was Nunnington Hall in Yorkshire. The story was all about one generation of the family who lived there in 1900, in whom I had no interest. There was only a passing reference to things that interested me, like the major work done to the house at that time by a famous architect, the house was full of needlework; quilts, bed hangings, wall hangings that got no mention, and that is just two of the things I can remember, there were others. In each room I entered the guide stepped forward and started telling their tale about the family whether I wanted it or not. I did find one guide who knew about the quilts but no-one had any information about the architecture, nor was there anything in the Guide book other than a statement that the work had been done and who designed it.
It is just having visited the two non-NT houses I mentioned and enjoyed it so much more because the guides were not intrusive but ready to talk, discuss, or find out information they didn't have, if you spoke to them. We overran our time at Temple Newsom because the Guide was so good and had such a wide knowledge of the house and its collections.
