We had breakfast there last October. My DH & DS6 were not interested at all in doing it but I had been dreaming about being in that Castle since I was a little girl! It was everything I had hoped for. The food wasn't brilliant but the whole experience was worth it. (We were on FREE DINING so didn't actually have to pay for it)
The complimentary photo package was also a nice keepsake.
We had an 8.30am ADR and got some great photos of the Castle & Main Street before park opening too.
