I had a bedroom and a toy room for DS1&2 when they were younger and it was great! If you didn't get toys tidied before bed it was no problem either, the bedroom was always tidy and ready for sleep. You can just shut the door to the toy room so you don't have to see the chaos when there's no time to clean it. I had friends who's kids liked to trash the beds every time they came over and the toy room kept the beds clean and intact too
