Haven't we done this at least 3 or 4 times before. The truth is that most of these options makes NO sense and are not feasible. They are specialty rooms that are not workable from a system standpoint. If it doesn't make sense for all units that size to be the way you suggest, no reason to do it.
OP here. Actually, what I was thinking about was for any new DVC's that might come along in the future - in those circumstances a lot of the options presented do make sense and would be feasible

My thoughts were more along the lines that almost all of the existing DVC rooms fall into the same arrangements and that in the future it would be nice to see some alternatives to the existing options. We are already seeing some of this with the treehouse villas. There is also some precedent for having different sleeping arrangements within the same room classification. This May we are staying at BCV in one of the 2 bedroom units that has 2 queens in the studio part - I would love to see more of this type of option.
Glad to hear all the different ideas people have for what would work best for their travel style.
