i have been on both ships. yes, I am an NCL loyalist, but think the lines are similar in many ways. In this case, there is no comparison. The Jewel is barely 2 years old and one of the nicest ships a float. the Majesty of the Sea is quite old, an ok ship, very small cabins and just not up to par with the Jewel. If you were comparing it with a newer RCI ship it might be a little different. I know you will love the Jewel.
