My experience in the past is they don't usually have them loaded into their system or ready to book right when they open at 7:00am. It sometimes takes a couple of hours before they are in there and can be booked, so I would call again in a little while just to see if they release them today. Otherwise just keep checking once or twice a day for the next couple of days. It sounds like they are coming out soon.
I'm hoping for AP rates to see if they are better than the come back rate that I have at CBR which is about $95/night including tax. If they are the same as the FL resident rate, that would save me about $10/night. But if they're not, I'll be happy with the rate I have.
I have to call to put in some requests and make some dining PS, so I'll also check.
