Hello Noelia! Some of the differences between Disney and the other cruise lines are that 1) Disney does not have a casino onboard, 2) The shows are all Disney Themed, and 3) You rotate dining rooms each night. As far as service goes, I personally feel that the quality of service is the same as it is on the other major cruise lines, and I feel the food is on par as well. It comes down to a personal preference. If you have any specific questions, please let us know and we will be glad to help you with your decision!
