, if I was logged in, I could always see the points option to book a room even if I did not have enough points in my account

Been around at least since last year, it is frustrating because I was looking for reward options for a trip in December but was unable to see alternatives to the stay I had already booked using points.
However at some threshold it allows you to look short and buy the remaining points, I booked NYE at the Doubletree TS with only 41K points in my account and bought the 9K points I needed.
