See, this is why I just could not talk myself into this house and be happy in the long run. If you have furniture you like and don't want to replace, then you'll be very disappointed if it doesn't fit into the new bedroom. Also, if you need space to get away from the kids now and then, I would think the lack of this ability would begin to wear on everyone very quickly.
We used to live in a very open house and I was THRILLED the day we moved out and into an older home with (gasp) doors. I need my space and quiet time.
