Looks like with everything, you are going to get mixed opinions. We started going to CM almost 12 years ago for our DD's 3rd b-day, she is almost 15. We have gone for breakfast every single one of our trips and many times also dinner. As far as breakfast goes, we have never been disapointed, including last time we went in November. We actually liked this past breakfast the best with the addition of the french toast (so good!) As far as dinner, we like it, not as much as breakfast but we do. I will say this past trip was not quite as good as in the past, but still good. I don't think we have ever had as good of character interaction anywhere and we have been to almost every character meal at least once.
We love CM, will always go. It isn't a trip to Disney for us without going.
