We have a family room still, but when we lived in a townhouse, we ended up moving DS's stuff and our clothing dresses into the master bedroom, and moved the bed to the small bedroom.
There were many reasons, including the temperature of the big room (heating vent was right over the bed so it could get stifling hot, but without the heat on it was freezing...in the smaller room we could keep the heat off and 3 sleeping people heated the room sufficiently), but ultimately, bedrooms are for sleeping (especially with a family bed, one wants other rooms for other stuff), and we didn't need a huge room for sleeping.
The only issue I had about that was DS spending lots of time in there if playing alone, with the bathroom so close. Paranoid about drowning and whatnot, though he never gave an indication that he would suddenly stick his head in the toilet (and he always announces *using* the toilet). It would have been an issue if he had decided he wanted his own bed while we were living there, but that request hasn't been made (he wants a racecar bed in a few months, but wants us all to sleep in "his" room in his racecar bed, LOL).
I grew up in a TINY house, and every couple years we would all switch around. The third bedroom was actually a former closed-off porch with a door to the outside, so my mom waited until we were not little kids to let us have that area, and then once she got re-married we switched up again and brother and I went to the tiny bedrooms and they got the back room. But my point is that I'm used to swapping rooms, a room is a room!
