IME, a 'playroom' tends to become a dumping ground and is rarely used for playing. Because of that, I voted 2 bedrooms, and I would split the kids by age. The big kids get the bigger bedroom with the little toys that are dangerous for a baby, the little kids get the other bedroom and maybe some of the bulky 'baby' toys.
I grew up in a family of 4 girls and 1 boy and the sleeping arrangements varied according to age and bedrooms available. When I was very little, we had to fit the kids into 2 bedrooms -- so my two oldest sisters shared, my middle sister, my older brother and I shared. Later, my 2 uncles moved out and my middle sister got her own room and I shared with my brother. That lasted until he got close to puberty and my parents split us by gender. So then, my middle sister and I shared a room, my brother got his own room (it was tiny) and my 2 oldest sisters (who were still at home, but in college) got the other bedroom.
I guess my point is that the sleeping arrangements you do for the next couple of years need not be permanent.
