If you are already globalist, it's hard to beat the Las Vegas runs (Excalibur/Luxor if you're ok with those or go up a tier or two for a moderate price). Otherwise, I don't think there's necessarily a go to spot, just depends on various factors and seasonality.

There was a wide availability earlier this month for HR Atlanta off peak at just 6.5k points. Not sure if that's still true heading into August.
If you can leave the country, HP Los Cabos, HH Mexico City, and HP Panama City are all cat 1s and often sub $100 cash rates.
