Non-related same sex children sharing beds on trips with community group

Why wouldn't it be?

I agree, why would it not be. Children often share rooms when on trips.

Why are you asking this question? Did something occur that you haven’t told us about? Please give us more details.

I would advise against it. For one thing you havent mentioned the age of the children. Another is sharing the " same " bed is very different from sharing the same room or a dorm living situation as one might encounter at camp.
