According to a phone call made to their daughter Monday afternoon, Glen and Margery Bennings, 62, are really enjoying their Carnival Cruise thus far. 'We've pretty much just stayed on the boat the whole time because there's lots to do and plenty to eat,' said Bennings, adding that while she and her husband were playing the slot machines in the casino the previous night, they met a couple of nice Yemeni tourists who seemed 'dumbfounded' by everything the ship had to offer. 'Gotta go! They're getting us all up to dance the Macarena!' At press time, the Bennings had not been heard from but were assumed to be enjoying themselves immensely.
