  2. If possible outside. More importantly make sure they have a source to pull fresh air in. Also be weary of odors when venting. Carbon filters are your friend. Sorry if you've all ready covered these issues. Just puttin it out there.
  3. If your venting into the hallway then the room is pulling air from the hallway too. Venting outside is best but dangerous especially if you have snoopy neighbors :cool: Venting into the attic is best and safest IMO but the attic will also heat your whole house but more gradually and to a lesser degree.
