Choice points ?
 

Recently did a paid stay at Choice - I do not normally do it

So wondering if I should earn the points to United - I am unsure how many Choice points you need for a single night stay nor how it works?

A Choice night cost anywhere from 6,000 ( very, very limited number of properties ) to 30,000 points. Obviously, the more points, generally speaking, the better the property. To me, the sweet spot for points redemption is 10,000-16,000 though YMMV. Choice almost always has ( though not at the moment) a stay 2 get 8,000 points promotion.
