It appears that a number of reply’s have overlooked the fact that the OP stated they were considering a RCCL cruise. While comparisons are helpful between the cruise lines the details about
DCL only is less so. Couple of points to consider.
- Yes many of DCL’s cabins have the split bathroom and it does give more room overall but mostly that is around the shower side
- commode area on both lines are pretty similar, small but workable and in general yes bigger than the airplane
- the shower on the Oasis ships really is pretty cramped
- especially if you are a pretty “regular” person then it is always an option to use facilities outside of the room, a good morning walk or workout give perfect access to the gym facilities where you can usually also find locker rooms with bathroom with showers
