I noticed that if a rate is available at another location but not at your location, it will place the check other alternate dates link on the screen. I also have noticed that it will put that on the screen sometimes if there are mulitiple properties and the rate is available on the date you select. However, if that is the only property with that rate and it is not available then you are out of luck. It is very fustrating even more so if you are looking at a one property town.
