We just spent 36 days on Jewel: 10/9/2023, 9/28/2023, and 9/14/2023.
She is a wonderful ship. The Concierge Clubs on Radiance Class are the best in the fleet.
The resident production shows are the same as on any RCI ship. There are no two70, Ice, or Broadway shows. There are also the same tired old comedians, magic shows, etc... that you will find on all RCI ships. There is always one great headliner show.
There is no CK, but the major specialty restaurants are all there. Safari Club is best.
If you want brand new furniture and the same tired old ports, spend double on Icon. IMHO, Radiance class ships have the widest selection of exotic ports and no cookie-cutter 7-day sailings.
