”A good number of cruise lines today still offer "traditional" dining, which dates back to the era of transoceanic liners: a fixed mealtime at the same assigned table each night. This leaves passengers with some degree of uncertainty, like where their table will be and who they'll be sitting with. Other
cruise lines, however, ask for preference on table size at the time of booking, and generally seat guests at tables ranging in size from two to eight seats. ”
You can still do it just do your research before you book
