Sorry, we can't help with accomodation; but I would say that, if can get DD there: do it.
I'm guessing that you know Sander already, but I can't overstate the contribution he and his team made in getting my DD into a vocational upper school.
She's done two years of Bloemmart Ballet School's Senior week and says it is the most intense intensive she's done (including RBS, ENBS, YBSS and Elmhurst) he works them hard, is so supportive and she learned so much!
Good luck in your search for accomodation!
