Apart from two minor issues with my hotel room, both promptly addressed by Hyatt, I did not have any disability issues at this con.
(I did have issues outside the con while attempting to navigate Alexandria and DC, but that's on those two cities, not World Fantasy Con. I also did get sick more than once anyway, but...well, I think that's more or less my status quo now.)
As long time readers know, this is not something typical of World Fantasy, which for the last several years have featured Disability Fail after Disability Fail after Disability Fail. So it's a major relief to find that yes, this convention can get it right, and I want to thank the 2014 World Fantasy Committee for getting it right this time.
