I'm sure there is no one correct answer here but I'm curious how folks do the math. Say a room is $100 or 10,000 points. It is east to say that's a penny/point (though it will be slightly higher due to taxes). But what if there's also an option at $40+3000 points. Are the points worth 2 cents each (3000 points makes up the $60 I'm not paying in cash for the room)? Or are the points worth 0.57 cents each (I spend $40 to "buy" 7000 points to complete the award)? Something else??
