That is what I originally thought as well but yesterday morning I was able to book for the 27th so my assumption was today would be for the 28th. I am on hold for Dining and at the opening prompt it said that one must have an onsite ressie with a check-in date of Nov 18th to be eligible today to book for Nov 28th as well, however, online I only have availability thru the 27th.....Frustrating!
