The only problem we had on the DDP was at Coral Reef. When we walked in and sat down the waiter was very nice, he saw we were trying to take a picture of ourselves and offered to take our picture, was very talkative, told a few jokes, etc. Then he asked if we were on the dining plan (I think most ask that up front, not sure) and his attitude changed immensely. He brought us our food. Didn't even talk to us when he did. Plopped it down in front of us. Didn't ask if we needed anything, never asked if I wanted another drink etc. He brought us our check when we weren't even done yet. Never once asking if we needed anything else. He treated us like we were a bother to him. Needless to say he didn't get any additional tip, and we will never eat there again. (not that I cared for it anyway...except for the dessert)
