I have cruised with Celebrity many times and wanted to convince my Princess-only sister cruiser to come over to Celebrity.
Well, after we (me, my sister, and our spouses) came back from this Caribbean cruise, I've actually gone over to Princess.
I would specifically say that the entertainment EVERY NIGHT was an embarrassment. I wouldn't necessarily blame the performers as much as the writers. The costumes and the backdrops looked old and boring. The scripts were pathetic- cringe worthy.
