I think you tip essentially a constant amount t on cruises. Room service is about as free as dining in the main room. The only time I would tip exceptionally is if someone went really above and beyond, or did something against policy, and in a lot of customer support cases, a cash tip separately is a better solution there. Or, if it is just exceptional service , calling the employee out by name to management a few layers above.
