Yes...I was disappointed in the GS on Serenade...and board her again this coming Sunday for her Panama Canal. We'll be in an OS for this itinerary...I took a quick look at the cabin while I was onboard and it's similar to my OS on Jewel recently however, the lighting from what I saw on Serenade is just as bad as the GS was. Lack of good lighting in the bathroom is just a pet peeve of mine.
Enjoy the Radiance.
