So, that is another case where it actually WAS available. It's interesting that it isn't just a matter of "it shows available online, but it really isn't" all of the time. For some, it shows availability and it really is -- you just have to call to book it. For others, it shows availability but it really isn't -- you call and they say that at least one of the days is simply not available. And, for others, they can't even remove a day from an existing reservation because it doesn't know to use their own reservation for the days to keep.
Pretty messed up. Hopefully not database corruption or something. But it is more than just a "display" issue where we see the wrong thing.
