We did 1 bedrooms for the first few years, but now just do studios. Found that we didn't really use the kitchen.
We don't use the kitchen, either, but we do use the jetted tub, the washer/dryer, the larger table, and both TVs, LOL. Makes the 1 bedroom more than worth it to me.And that's especially true now that DVD has remodeled the studios to include that awful bed/table combination under the TV.
