Mickiethepooh,
I had a feeling someone might post such a comment, and I don't blame you. This is a "must do" thing for the young girls who will be in our travel party and, unfortunately, we had to make the reservations before we knew exactly what days we would be there. Thanks to the hoops you have to jump through to get a decent airline ticket these days, the late release of the AP rates on Disney hotels, and the impossibility of getting CRT unless you call within 10 seconds of it being available, this was the only way I could guarantee a seating. I wouldn't be surprised if many others weren't in the same situation.
I had hoped to make up for it by posting my cancellations here to let people know they would be available since, as you say, many people probably give up after the first try and never call back.
If that's not enough for your, perhaps you'll take satisfaction in knowing that I had to wake up at 4:00 every morning for four days straight since I live on the west coast.
