I have never been on any other cruise line than DCL. Two 7 night cruises with my family in the 2000's, one 4 night with my husband two years ago, and we are going on another 4 night in a month and a half with my in-laws and brother-in-law's family. My husband thought that was the best vacation he had ever been on. I will say that we are Disney lovers, got engaged there, got married there, run the runDisney races, etc so that was part of the draw but not all of it. You can't match the quality that you get from Disney, you just can't. We could care less about a rock climbing wall or any other 'games', a shopping mall, other restaurant options, and most especially we could care less about a casino. When we were on the Magic at port in Nassau, I remember looking over at an RCCL ship and thinking 'why would I want to go on that, it looks so much less appealing.' It just looked dirty and not fun. Now I have no idea what ship it was, so maybe the new ones are better. I LOVE the jealous looks from other ship passengers when my Disney ship pulls into or out of port. I just have to laugh. We do not have kids yet so maybe that will make a difference someday, but I doubt it.
