We are sailing on Sky in March, and the latest dining time I have found is 7:30. I have to disagree with those that told you to have two people make reservations for six. We were recently on Caribbean Princess with a party of 14. I made the reservations for all 14. We were at a table for eight, right next to a table for six. I think you have a better chance of getting tables near each other by doing it this way. It will still require talking to a Head Waiter, or MD, or DRO, whatever those are. ( Can you tell I hate using letters, not words?) We all went to the Crown Grill one night, and simply told the Head Waiter about it the night before.
