Where? I've booked 2 studios at OKW and had them in the same builing or in the same section of buildings. I once booked 2 1 BRs at BCV and one overlooked the pool and the other overlooked Epcot. They were directly across the hall from each other.
I don't think you can ever get adjoining studios because of the way the units are set up, but I think you can get them close or across the hall like my 1BRs.
I had booked 4 studios and a 2 bedroom for our GG last December at the BWV. 3 of the 4 studios were dedicated ones, very close to each other on the same floor, and the other was next to our 2 bedroom, again all on the same floor. We were very pleased.
