We also had problems with single group. We had assigned dining & they took our table. We went to the Maitre D & change our table. Then the next evening, we went to our new assigned table & guess what? The single group took this table so once again back to the Maitre D again & he changed our table again. We went guest services & they informed us they do not handle dining room problems! She called the Maitre D & I explained that you don't want to honor assigned dining then don't have it. He said this was a large group & they just did what they wanted. Finally, I said call security If they are taking over assigned tables. I will not be moved again! After that, we finally had our table. I remember seeing you guys in Ocean Plaza one evening having a great time.
