The girls are in one room, and the third bedroom is the toy room. Works well, they like being in together and I really can't stand having toys all over our lounge room.
DD2 still needs to be sat with when she falls asleep, and DD1 likes it when I stay with her, so makes my life much easier so they can now go to bed at the same time. Also only need to heat one room in winter. Lovely.

Go for it, if you don't like it, change it back!
