On the
Queen Mary 2, Jason and I were assigned to a table for 12 (though the seating diagram, in our cabin, showed it a table for 8).
On the first, we met two of our table companions, two lovely ladies from the East Coast, and waited to see who would be joining us.
Turns out, the others were a group of men, one of whom was livid that they did not have a private table; he made quite a fuss, and refused to sit with us. His group was soon escorted out (they might have been reassigned to the early dinner seating).
After that, the ship staff reassigned six others to our table, a retiree from Florida, a mother and daughter, a lady from Essex, and a couple from Surrey. They were all great people, and I definitely enjoyed their company. It also made it nice to run in to each other, at the book store, walking on deck (on the last day at sea), being at the front of the ship when we came in to New York, as well as waiting for our turns to disembark.
On the
Queen Mary 2, they do have the Food Court area on Deck 7, where people can sit at tables for 2 or 4, which can make it easy for one to dine by himself or herself.
