We just got back from Orlando. We were at SeaWorld on June 14 from 9am to 9pm. We bought the all day dining passes that morning as we entered the park (arrive 30 min prior to opening if you do this) and easily ate $30 worth of food and each (DH, DS 14 yo and 2 DD 11 yo). My kids loved getting whatever they wanted and just waving their wristband at the cashier. You stand in the regular cafeteria line (only once was this a real line) and select a entree, side or dessert and drink. Drinks can be fountain drinks in a cup with ice or bottled water. You can go back and do this as many times as you want. The cashiers always waved us on as soon as they saw our wristbands.
We went in for drinks, fruit and fries early in the morning, ate a huge lunch, stopped for another snack mid-afternoon and ate a late supper. We stopped in for drinks/water a few more times. The food is good, better than most them parks and varied. My husband enjoyed barbque. We had salads. They had watermelon that was great on a hot day. Also they had strawberries with a little cup of fudge to dip in. I was a little disappointed that we never found ice cream in the dining plan restaurants but my husband and kids had chocolate cake, pudding, cheesecake and a delicious cherry cobbler. The entrees were priced $6-$9, the fruit $3-$4 and the water about $2.50 so we easily ate $30 each. Other than the bottled water the food is not packaged for takeout, but no one watches the door to see that you eat it inside and we walked out with fries, drinks, and bowls of watermelon a few times.
