One thing I am good at is avoiding pretending that a hotel charging $700 a night or 70,000 points is actually "worth" 1 cent per point. If you definitely need that hotel and would otherwise pay cash, then you'll find a few examples, but not many. Most people using their own cash wouldn't actually pay 320 euros for OR Tambo - they'd stay somewhere cheaper and take a shuttle bus. Value isn't what the hotel is charging - it's what you'd pay for the room.

But hey... everybody's entitled to their own delusions of how they are "maximizing".
