If they are trying to reduce the number of calls from AP holders asking about discounts, their website is not going to be as much help as they think. As implemented, checking for AP rates on their website is tedious. You enter your dates and see what comes up. No discount? Try shifting your dates by one day. No discount? Try entering your dates one day at a time to see if one particular day is causing the problem. No discount? Try a different set of dates... etc, etc... all with the inevitable internet delays between each click of the "update" button... After a few rounds of this, I'll be picking up the phone to CRO to say "just tell me which dates have the discounts available so I can then go back to the website, plug in those dates and book my trip."
They need to display a calendar showing the rates for each room type on each day so you can see which days have AP rates available for the room type you are interested in. That type of display makes it quick and easy for people to figure out which dates to book and whether you need to shift your trip dates to get a discount and will eliminate a lot of calls to the CRO.
Sorry for the griping, but I'm a software engineer and whenever I see something implemented in such a user-unfriendly way it really gets to me!
