OKW is the only studio with 2 "real" queen beds.
All other studios have a queen bed and a couch with a pull-out full bed. (More seating options in the day, but not as ideal for sleeping.
FYI, in addition to the Queen bed and Full pullout, VGF and VWL studios now have a pull-down bed. (I think its a 5' long trundle bed, good for a kid or a pre-teen that would rather overhang on a bed than share)
VGF studios also have a split bathroom with 2 showers.
