It seems like a slow day, so let's talk guest rooms.
Scott really wants us to have a formal guest room. Nice bed, dressers, empty closet, etc. Personally I don't want to spend the money on one (we would have to furnish a bedroom from scratch) or give up one of our rooms for the maybe once a year that it is used. We currently have the rooms assigned as a nursery, sewing/chinchilla room, and our own bedroom.
I am thinking of designing the nursery to be used as a guest bedroom if necessary, and we currently have a futon in there that does double time as a couch or full size bed. I slept on the bed for over 10 years, so I think it's fine as a bed if I add my mattress pad to make it a little squishier. If we turn it into a formal bedroom (bed, dresser, spare closet, etc) then we would have to relocate the chinchilla, all of my sewing stuff, and (at least in my mind) devote a room to "looking pretty".
We also have a couch downstairs that pulls out into a full sized bed. There are doors which close off the upstairs from the downstairs, so a guest would also have privacy if they slept downstairs. We would just tell them to open the doors when they were ready for the day and we would stay upstairs otherwise. There is a bathroom downstairs.
So...give me your opinions. Is it worth spending a couple grand to make a formal guest room that will be used once a year, if that, or as a guest would you be ok with a futon/couch bed in a private portion of the house?
