First cruise ever. We have 2 rooms, 7 people. The first room is a Family Balcony, the other an Inside. I am trying to plan our specialty dining. With the Free at Sea, the balcony has 4 specialty meals for the first 2 people, the inside has 1 specialty meal for the first 2 people. Can those 4 specialty meals be shared or do they only belong to the person they are listed under? Can you use up multiple credits in one meal to cover the table? Trying to figure out how many extra meals to purchase. Thank you!
