Yes there is that much more room. The washer/dryer is great and there is that large white box that keeps beer cold. There is another box that people tell me can cook food (never tried it) and another box that washes dishes (do rocks glasses count?). The bathroom and whirlpool tub are better than a studio, and the king sized bed is great.
You will love it. My DW is now pressing for more 1BR stays and less studio stays even if it is just the two of us. According to her, life is too short to mess around with studios. Of course our next trip is in a studio but that is because we are traveling with family, and there is something to be said for separate alone time!
