DD to share room & have toy room or not??

[peacenow]

Hi, in our house we have a large 2nd bedroom & 2 tiny weeny other bedrooms (as well as our room). My eldest dd (11) has a tiny room & so does youngest dd (5), middle dd (7) has huge room to herself.

Have been thinking, should we get bunk beds & put the 2 youngest together in the big room & turn the other tiny room into a play zone or should my youngest 2 dd's have their own rooms?? Does any-one have any experience of sisters this age sharing or any other comments??

We have swapped rooms around more than once so that one DC does not get the biggest room/have to share all the time.
I gave the biggest room to the eldest when he was in the Sixth Form and then the second one moved in when eldest left for Uni!
They all preferred not sharing and liked to have their own space - not surprisingly, being one of five.

Thanks Greenwing, useful comments!!
