Deb Wills' site says the $23.99/adult includes Coffee, Tea & soft drinks. I don't remember paying any extra charges on our bill this past August.
My DH, myself, DD(4) & DNephew(6) went here in August and we absolutely loved the food an the entertainment. The kids enjoyed the hula hoop contest and the coconut races too. We have plans to return next weekend for our trip.
Disappointingly, there have been several posts about meat being charred on the outside, but raw on the inside. I didn't encounter this at all on our trip. I will pm you or post again with our 'Ohana experience once we return.
