This is my thinking, I don’t see how they could make things easier, to me they would just take up room in the case.
I’ve just got back from a weeks UK holiday, older 2 DCs had their clothes in small carry on size bags. Myself, DH & youngest DC in the big case. DCs socks underwear and clothes packed together on one side of the case, underwear at the bottom everything else packed with like for like (tops, leggings). DHs on the other side, mine in the middle. Everything packed in order so could just be taken out and put in draws or I could go straight to it.
I always pack toiletries/medicine separately in a big sports bag with shoes in the side pockets.
Coming home dirty washing put in a giant bag for life which we’d been using for washing all week. Remaining clean clothes in the suitcase and kids fill their bags with their holiday wares or they get folded and put inside the case or big sports bag.
If going overseas we use 2 suitcases but on the same premise with organising as I pack and one case used for dirty washing coming home.
I’ve never had problems hunting for things on holiday.
