My pool doesn't have family rooms. When I take my (8 year old) daughter swimming, where do we change?
Maybe its beat to change before you get to the pool. Bring extra towels for the ride home, or dry off in the sun before you leave.
In my day it used to be that kids had to accompany their parent into whichever changing-room was designated for their gender, regardless of the kid's gender. Not sure about now, though. I'd have thought the swimming bath staff themselves should be able to best advise on what is today's protocol?
