Ended up booking a 15K award night at the HIX in central Cape Town (even advance booking was over ZAR2,000 so good use of points) after flight change got me in a day earlier. Had booked the original two nights on Cash&Points award at the Westin back in July but had hoped to change it to a full revenue, but not at ZAR3,000+. Still, I've been traveling down there in January/February for years and never found rates this high before.
