AIDAprima pool area isn't that big either. But a lot of fun for kids.
I have been on the Royal Caribbean ships (US) as well - huge pool side for kids. I don't remember the one for the adults. If an US ship is an option for you (they are also sailing the mediterranean sea) than this might be something to look at.
I wrote a wish list and have it to my wife. So she will do the search 😁😎
Al companies are fine with me. As long as they speak English or German.
Thanks for all info and replies!
