I would call once a day, every day until I got it. I would try to pick a time when I thought I wouldn't be on hold for too long and just check in quickly. Everyday people may cancel, so you just never know when something would become available.
YES, Yes, yes...call back everyday. I just scored Cinderella's Royal Table for our visit in Sept today...I called each day! What is even greater is that we are traveling during their free dining promo (we booked too late for that!) and most restaurants are BOOKED SOLID.
NEVER GIVE UP!...Just like they say...all you need is Faith, trust and Pixie Dust!
I've been calling twice a day for HDDR...9/6 7:15 show is the only one we can go to....we just booked last week so we are behind on or ADR's....and everything is booked! I'll keep calling but I have more hope for cancelations closer t the day we want to go...I really want my son (4) to see this on his first trip...the show is magical!
