My daughter (8) likes to go with my brother (22) and my son (5) to the pool --->

Is it ok that she goes through the men's locker room with them ? It's an old building with no other way for her to go though unless she goesthrough the womens ALONE which they know I do not like. I much prefer both kids be in his sight at all times. There are usually not too many males in there the times they go. She waits already in her suit and a beach towel, and when her uncle changes or showers he's careful to face the other way so she doesn't get any full frontal shows. The kids have been going since beginning Sept (an indoor park pool) and they love it.
