Honestly, we've done both and both are manageable. However, a 1-BR is worth the extra points to me, because I get a full kitchen, a washer/dryer and an additional room. With little ones, it's nice to have a room where you can put them to bed, shut the door and still have a place to go watch TV or a movie. Like I said, though, for our family of 4 (DS is 12 and DD is 5), either works!
