It took me 4 days to get our CRT breakfast res., but I finally made it through.
Here are a few pointers:
Call a day or two early and find out which prompts you need to enter (press 1 for..., press 2 for ...) write these down so you won't have to listen to the entire message to know what number to enter.
Have the entire phone number, except the last digit entered, about 10 sec. before it is "officially" 7 am. EST, then at the last second dial the last digit and get ready to enter those prompts that you have written down.
When the cast member answers, quickly, but politely, ask for the earliest CRT res; no time for chit-chat now!
Best of all, Good Luck!
I know how hard it is to get this res, so I told my dd7 that you have to call Disney and let them know that you would like to eat in the castle with Cinderella and then she chooses who gets to eat with her.
When we finally got through, I had my mom who lives in Florida mail my dd an invitation from Cinderella inviting her to breakfast. She was so excited when it arrived in the mail! This was also a way to avoid disappointment if I was unable to get through. I explained that the castle is very small and not everyone who wants to eat there can because there aren't enough tables.
I was also told by the castmember that some people do cancel at the last minute, as you must leave a credit card deposit and to try 2-3 days before arrival to see if there have been any cancellations. We did not get CRT for the day I wanted, but at least we got in!
Hope this helps!
