Just re read some of the other posts. Cato you should come and look at the school and others to make sure this would be the right place for your DD, you definitely can't send a child halfway across the world based on a prospectus.
Boarding at RAAS suits a certain type of child, outgoing, loves activities, sociable. I don't think it suits a shy loner type but then I don't think boarding at any school suits that type of child.
Ofsted have never reviewed the boarding facilities, that is not in their mandate. The school scored good with some outstanding elements based on the new stricter criteria.
The boarding facilities are not run down quite the opposite, the boarding facilities are purpose built houses at one end of the site close to the main school. Every house has 2,3 and 4 bed dorms, a large sitting room used by the kids, with x box, tv, books, piano, a large classroom with around 40 computers and desks used for prep, a Skype room, a large games room containing table tennis, pool table, etc etc plus all the usual showers, towel rooms, boot roms etc. they are not 5* luxury but they are all clean, well kept. Because the houses are effectively on campus right outside for the kids to use 24x7 are the astro turf sports pitches, indoor swimming pool, outdoor gym, indoor gym, horse riding school, tennis courts etc etc . There is a purpose built 6 form center with their own study rooms.
The head master is definitely like marmite. I am not a fan however I did like his ethos of take the whole child and bring out the best they can be across all dimensions, social, ethical and educational.
Lots of children stay at weekends and there are lots of subsidised trips, activities for them to do on Sundays if they want ( Saturday there is morning school and most boarders seem to go to the local town for coffee shopping in the afternoon)
Finally the most surprising thing for us is apparently according to my 11 year old foodie DS the food is delicious. We had told him tales of DH and I boarding experience of cold overcooked cabbage, spam fritters etc but not here. On Sunday's if we have DS with us he has insisted we take him back early so he can have his school Sunday roast dinner !!
