If you and your husband like to "stroll" on deck, then you will have a lane to stroll on deck 18. The joggers will have a separate lane and you will not have to move out of their way as you would on the promenade. If you are a relax and read a book person, there are full teak loungers on the promenade deck aft, on both sides of the ship. All of this is weather permitting.
There are no perfect ships in the cruise industry. Each ship is built to please as many cruisers as possible and make as much money as possible. The industry knows what features the majority of cruisers utilize and tries to incorporate the features in their design. Some things one might enjoy and declare a must, might have little or no value to another. Thats why it is important to research the cruise line and it's ships before booking.
There are so many choices of ships and cruises to make to achieve the cruise best suited to your needs. You can meet all or most of your requirements and have a super cruise. Just do your research.
