Keep trying is the best advice. We have all our ADRR's in place but I know as things come together (now coordinating with the Grandparents) some of our plans will change, and further changes will no doubt happen at the last moment. I alway cancel ADR's as soon as possible, I'd hate to be responsible for someone else not getting a seating. I'm also convinced they hold some seating for walkins & resort guests, I was amazed at how often we were able to get seatings that morning at the resort counter or the service desk just inside each park (can't remember what they call it).
BTW - I've booked on the 18th of Aug. for Le Cellier, I have a strong suspicion it will be cancelled, just can't tell quite yet. Maybe that will help you.
As to CM's looking at all your bookings, I believe if you reference your phone number, they pull up a list of all, when I've made changes they've been able to quickly see and review my other bookings.
Good Luck, don't give up.
