I was going to use my points for my european road trip this winter, knowing that some nice properties in UK and Italy were going for 8000 points\night during that time. However, I was not able to book the rooms yet, since my window is 75 days in advance.

I've just checked and most of the properties in London now are at 20K, and the Italian ones are at 10-12K. Those are the exact properties Choice have been teasing me with their 8K rate, but when the time window approaches, they suddenly just go up in price.

Is it a fair business practice? Does it look like a devaluation?
In addition, there are no longer 20K Manhattan properties, only 25K.
