It is completely different from my experiences with the exception of the wine glasses and sommelier.
I have experienced only excellent, friendly service on princess along with good food. Personally, while Reidel glasses are nice, it doesn't affect my cruise that they don't have them. I can understand the frustration with the long wait for the wine, though.
My next cruise is on Celebrity, but the following cruise is on Princess. They are very much alike, but like all things, people view things differently.
Happy cruising! 🛳
