According to buffet/AYCTE (including tax, excluding tip):
bfast . . . 10/02/2016 Adult: $34.08, Child: $20.24
lunch . . . 10/02/2016 Adult: $44.73, Child: $26.63
dinner. . . 10/02/2016 Adult: $44.73, Child: $26.63
For me, I booked dinner. Besides not into breakfast food, I just couldn't justify paying $34.08 for breakfast food.
P.S. I should also mention, I tend to "over eat" at buffets and I don't think I can walk around all day at park after stuffing myself. Since price for dinner was same as lunch, I chose dinner so after "stuffing" myself, I will go back to resort to go to sleep! LOL!
