That 1BR and the studio in 30 were both renovated but not released for room inventory during the past couple of years. Thus, there have only been 20 1BRs and 20 studios available during this time.
That being said, depending on your love of and desire for the nostalgic feel the old rooms provide, the new rooms may or may not be a welcome change: expect a muted/earthier color scheme, updated lamp fixtures/curtains, sleeker looking cabinets, no wall sconces, no painted tiles in the kitchen's backsplash, soaking tub replacing the jetted tub, et. al. The rooms definitely will not remind you of a fishing lodge which was the original storyline that has, more or less, been followed over the years.
