Okay so this isnt really a question that is easy to answer with a poll. Like a 7 night cruise on which ship? Where are we? Because I might use it on cruise where I care about ports maybe... Also what hours is it open? What is the menu? Is it a buffet? Sit down?
For instance- 7 nights on the Treasure, limited hours 5:00-7:30 sit down, limited menu (lighter notes)- Zero
7 nights Alaska and I cannot get late dining? Maybe once or twice at most
ETA- Also important, is it a ship cruisers have been on before or not... I think
DCL vets who sail frequently are more likely to skip rotational dining than new cruisers
