They've raised the point cost for South Bank to 180,000 Hilton Honors points per night as the standard reward rate from 130,000 points. Seems to still be plenty of availability at that rate - choices are either the 2 BR Boathouse or the 1 BR Boathouse. The rate in cash is pretty steep, but booking 5 nights with points for 720,000 would be the equivalent of a studio penthouse at The Quin converted plus a couple of FNCs to round out the week, making it pretty manageable. We've got a ThirdHome exchange over in Grace Bay for a week after this then are back here for another 5 nights using points (at the lower rate). Might come back again in the future....
The unit has a quite usable kitchen and staying here comes with free breakfast daily for two people.
