Bico and HG I'd rather not say which house we visited might help identify us and I wouldn't want anyone at WC to know my negative thoughts!!
HG While we were having the tour, most students were in their Saturday classes. Then, while we were having 'lunch" on the lawn outside New Hall (I think), the students presumably were having their own lunch. By the time we visited the houses (around 1:30 or 2, I think) the boys had finished lunch hence, our surprise not to see many engaging in any sorts of recreation around campus (other than those who were playing in the cricket matches). Our guide told us he planned to play tennis in the afternoon and then "go to town". When I asked what the boys did in "town" he said "not much; just go around shops". (He was a lovely boy, by the way; just seemed a bit uninspired...). Where DO boys "play" kick a ball, throw frisbees, etc on weekends? Other than the cricket pitches and the garden around the house we visited, it wasn't obvious where boys might be allowed to have kcik-abouts.
Re my comment about the buildings: I wouldn't expect our student guide to tell us the age or history of buildings but I would expect him to at least say "that building is one of the oldest buildings" or "that's the only surviving of the original buildings", etc. Frankly, he didn't seem to know what to show us indicating either a lack of imagination on his part or poor instructions from the registrar. Had we not asked to go into the library, he would have just pointed to it. As we did ask, we went in but he didn't know which way to take us once inside the building, nor did he tell us anything such as "here are the fiction books", "here's where we do on-line research" or ANYTHING that indicated how he, as a student, uses the facility. It was just very odd. What we observed on the day other than the two teachers I mentioned above -- did not manifest what we had read and heard elsewhere.
I'll definitely give it another chance.... though my creeping positive view toward boarding has been challenged by this experience!!
One more comment: I was very surprised by the people at the Open Day. Seemed to be quite a few from Pilgrim's and Horace Hill (?) which are feeder schools (and, hence, I would have thought parents already knew the school. Very few (if any) boys from London schools (Sussex House, Wesminster Under, The Hall, Wetherby Prep, etc) -- schools which tend to send their boys to selective boarding schools such as Winchester.
