I would echo what others have said. The experience is mostly he same. I would describe things as a bit “simpler”. Food, entertainment, activities, stateroom service, etc. all very good.
The biggest change we noticed was in the MDR. Service just seemed “off” to us. Less attentive, rushed, forgot things, failed to offer coffee, etc. Nothing major, but just off the quality we had seen previously. Perhaps this is just temporary or a fluke of our specific cruise.
