Who has information on nudist cruises ?

I’ve been thinking about joining the Big Nude Boat for a few years now.

Meanwhile you can even book with Oböna and Miramare. In 2020 you are on the road for one week, in 2021 even 2 weeks.

The whole thing is also quite expensive. My problem is that there are only a few reports about this trip and there are a lot of open questions. Maybe one of you has made a trip with such a ship and can report. Maybe you could do such a nudist cruise with a small group?
On the Aida you have a nudist deck, on this trip the whole ship is nudist…or not ?
I actually imagine it in such a way that I can stumble over the deck with heels all day long. In the evening naked to roulette and of course stark naked to the disco. I have already heard that you have to get dressed in most restaurants.
I have read that certain nudist beaches are frequented. Do you have to get naked when you disembark or do you have to get dressed first? An important question for me: is it allowed to take pictures?
So……if someone can give first hand information, give it to me !
If it is already so expensive, the expectations must be fulfilled.
