I have been on quite a few cruises. Some of them have had very strict dress codes for dining room (Holland America for Alaskan cruise) Most are not as strict. I have done many on Royal Caribbean and never had an issue with the dining room attire as long as not shorts and flip flops. Even on "formal" night, my husband and I have gone to the dining room in casual clothes. I would recommend that you take some anti-nausea meds with you just in case you experience seasickness. They do sell bands you can wear on wrist if you don't want to take meds. Have fun and just spend time relaxing and renewing your love
