Well, we just came back last week and I can tell you that if you are on the dining plan the waitress figures it out for you. When she brings the bill to you and you give her the dining plan card the waitress then disappears to adjust the bill. When she returns she gives you a receipt for the dining plan that let's you know how many credits you used but, then she gives you another receipt and says this is the balance for the gratuity. The gratuity is figured out and circled on the receipt and that is what you are "expected" to pay. It happened at ALL the table service restaurants we ate at which were:
The Garden Grill (family style)
O'Hanas (family style)
Cape May Cafe (buffet)
Whispering Canyon Cafe (family style)
Chef Mickey's (buffet)
Crystal Palace (buffet)
Believe me , they make sure you know that the tip is not included and when they hand you the receipt with the "tip balance", they say this is your balance I'll be back in a moment!
