If no one cared about formal night, then the cruise lines would do away with them. When the cruise lines stop advertising formal or dress up nights there will no longer be a need for this type of conversation. Until then, the point remains that the cruise lines sell people a vacation with a formal night, with a published dress code where they am told and therefor expect everyone else in that dining room, on that night and that night only, to be dressed in accordance with the published dress code. It is the fault of the cruise line for not enforcing their own policies as well as the fault of the people who feel they are above the stated policy, whatever the policy is on each different line.
There are multiple other restaurants and buffets on cruise ships for those who don't want to "dress up" to the code for that one night only.

7-night cruises:
- First night is cruise casual—no swimwear or tank tops
- One pirate night or other themed deck party
- 3 additional cruise casual nights—no swimwear or tank tops
- One formal and one semi-formal night—both give you the opportunity to dress up and take advantage of the onboard photography services. Though optional, we recommend dress pants with a jacket or a suit for men, and dress or pantsuit for women
