You will love RSSC, you can't go wrong. The ships are quiet and romantic with subdued and elegant entertainment.
Just FYI, they had a recent dress code change, it is trending more toward the casual, here's the info:
Daytime Dress Code (until 6 p.m.)
During the day, resort style clothing (including shorts, warm-up suits, jeans and sneakers) is acceptable in all public areas. Bare feet are acceptable only on the Pool Deck. Note: Bathing suits, while acceptable at the Pool Bar and Grill, are not considered appropriate in any indoor venue.
Evening Dress Code (after 6 p.m.)
Two types of dress code have been established for evenings in public areas: Elegant Casual and Formal Optional. The number of Formal Optional nights is dependent upon the length of the cruise, as follows:
• Cruises of fifteen nights or less will be Elegant Casual for the duration
• Cruises of sixteen nights or more will have two Formal Optional nights
Elegant Casual: Skirt, or slacks (no jeans) with blouse or sweater, pant suit or dress for ladies; slacks (no jeans) and collared shirt for gentlemen. Sport jackets are optional. Note: Jeans, T-shirts, baseball caps, shorts, sneakers and bathrobes are not considered appropriate in any public area after 6 p.m.
Formal Optional: While guests are welcome to dress each evening as per the Elegant Casual dress code, during Formal Optional evenings, guests may opt for a more formal choice of clothing including gowns and cocktail dresses for ladies; tuxedos, dinner jackets or dark suit with tie for gentlemen.
