Our cruise was great value. The "Marie Antoinette / Louis VI" decor was good fun - lots of mirrors and gold, like Versailles.
Restaurant and meals were excellent, drinks unlimited, service great.
We had the lowest deck cabin, with just a high window, but it was fine. We spent all our free time on deck, or the lounge etc. I wouldn't pay more for a French Balcony or Full Balcony, on this or any ship.
Great. I wouldn't spend more for French Balcony or Full Balcony. You just don't spend enough time in the cabin for it to matter.
