We just got back from the Grandeur of the Seas last week and have to agree with the responses above. She's a beautiful ship with a great service staff. With the exception of the photography services ( a concession run by an outside company ), I have nothing but positive memories from this cruise. As far as your husband wearing jeans during the day, that should not be a problem at all. My recommendation for dinner in the Great Gatsby Dining Room would be for slacks (Dockers or similar) and a nice polo or golf shirt on casual nights, and a dark suit on the two formal nights. Enjoy your cruise!
