We were one those posters who had a bad PSB experience. The morning we were there the food was terrible, undercooked and barely passable. I didn't even recall cinnamon rolls and we were only there a few days before Tink was.
The service was not too good either. (I requested some warm milk for my dd's oatmeal that I brought with me because she doesn't like eggs, but I would have never let her eat the food we were served anyway), the server couldn't fulfill that "special request"....luckily I had a peanut butter sandwich with me to give her and despite that I still had to pay $9.99 for her which I was prepared to do, but I think I still could have gotten warm milk for her for that.
I barely ate a thing, I guess $30 for Juice and coffee and some princesses swinging by the table 30 minutes after we got there in a 5-7 minute whirlwind was enough to keep me from going back especially when I haven't heard back from WDW yet after explaining our experience. I was quite disappointed.
This was the first complaint I've ever had with a WDW restaurant. A friend who also went to this breakfast some months back also thought it was terrible. But, many posters have posted having great experiences. I wouldn't get up early to get it, I'd try for CRT's first if you're going to wake up early. I'm hoping the new Cinderella dinner will be better, we're trying that next trip. That has a better chance since the dinner has been around just with different characters. Good luck, all of them are worth trying at least once.
