Only mod I've ever stayed was PO-R but I loved it. Yes, the grounds are huge, but a lovely walk and we usually have or rent a car with us, so even if we're far from a bus stop, it doesn't hold us back all that often.
Out of the three remaining, based on what I've seen on video, seen when i've visited and read, I'd be most interested in staying at CSR, followed by POFQ and then CBR.
