No, it did not work for me. When I pressed 1, I was told the same thing. I was also told that anyone who has "slipped through the system" would have their reservations cancelled by the system. I honestly don't believe this. I think I got a disgruntled agent. I told him that this seemed unfair since many people might not know the 90 day thing. He said it didn't matter - that they should have been told by the agnet.
Then, I called again

Tried the same thing.
I got another agent who immediately asked for my reservation number. She said that since I wasn't checking in until the 22nd, I couldn't book until tomorrow. Honestly, I think they should all be doing this.
I am just going to play fair and wait until tomorrow. Hopefully I will get the ones that I want if I call right at 7AM.
