I just got off the phone with them for the third time this month. But this is the first time that I wasn't given a date as to when the discounts would be available. My CM today stated that there has never been a set date, and that the hope to get the rates loaded by december 1st (last date I received)was because DL is upgrading their reservation system... apparently my CM figures the rates will become active during the upgrade. I asked if there were a set number, and my CM said it was based on the total percentage of standard rooms booked, not on a fixed number available. Unfortunately the end of the story is that we just have to keep calling until the rate is available, or DL decided to not offer it.
