I agree, it can be a little uncomfortable sometimes but I find it a good idea with young children.
I am faced with the dilemma of which changing room do I send my young boys into.
I dont want to send them them alone into the mens changing room.
Yet, the eldest has turned ten and at some point, ladies will not want him there in open ladies changing facilities.
So, the communal thing, with cubicles, is the answer for me and my kids.
There are usually bigger family changing rooms which are excellent.
I hate coomunal changing rooms in shops, where they are straight off the shop floor!!
the curtain never fits and at any moment someone might pull the curtain back.
I must say also, that my boys have crawled along on their tummies looking under every curtain to see which one im in.
Thank goodness the other people found it funny and didnt get annoyed to see little faces appearing under the door!
