Turning the pool table loft area into a full-on game room, or maybe even doing a projector screen with a home theater or video gaming set-up there - that could be a huge selling point for families looking to book a stay with amenities and spaces that will help keep their kids occupied and entertained.One note on the existing hot tub: having an awesome, well-running, clean hot tub can definitely help you command a nice premium on your STR bookings.
