If you have no kids I would try another cruise line first. There is so little to do on the Disney ship for someone without kids, all you will do is sit around, look for someone to talk to, try to find a place to lay in the sun, and spend most of your time watching out for kids. It is a pretty ship but lacks in entertainment for adults.
The shows are not broadway style shows as everyone would like to compare them to. They are Disney story shows, Fairy tale characters and the likes, and really are darn right boring to most adults and very exciting to young kids, unless you are a real Disney lover. The ships are without casinos. Disney doesn't have to worry about casinos because they get the money up front and don't give it back.
I think you would have to be rich to pay $75.00 per person for a Remy sitting. I have a few coins but never would spend that much on a dinner for myself and whoever is with me, especially since the meals in the dining rooms are just as good for most persons. I would never spend $150.00 for a meal for 2 plus the beverages.
The ship is beautiful, but without a lot of the different adventures that are on other ships. So if you just want to lay around for most of the trip and not really worry about anything you may enjoy the
DCL. If you are active and like to participate in many different fun activies look at one of the other cruise lines
