Thank you all for your opinions and advice! I think we will take her to the kids club, see how she likes it, and tell the counselors that she doesn't understand English. And then try leaving for a moment.

Children of that age may play alone or side by side, they don't necessarily need "friends" to play with. Or then, as Travelhound mentioned, they can use hand gestures to communicate with others. I am sure it goes well :)

We will cruising in January 2016 on the Adventure of the Seas (Southern Caribbean route). Our daughter is 3.5 years old, and she's an active and outgoing child. We come from Scandinavia, speak a rare language, and our daughter doesn't understand or speak any English (or any other language than our native language). I think she would love the kids club but is it even possible to leave her there if she won't be able to understand the counselors? Should I stay there with her the whole time, or will they even let me stay there? Or are there time slots when anybody can get in (even parents with their children)?
