You can reserve 2 studios at 1 time or 50 if you so desire. Our guide in 2002 said that people will often rent several studios for a wedding.
However, I don't think you can have adjoining studios since most studios are attached to 1 bedrooms. You may be able to get something close together.
In April we reserved a 2 bedroom and studio for a large party. At booking, we were told that we would not be close together because of the SMOKING studio. However, we were not close together at all, and they gave my sister a non-smoking studio. At BWV the 2 bedroom was on the 2nd floor above the Big River Grille and the Studio was in the Village Green on the 3rd floor. If we have to be separated because of the smoking issue o.k., but if that's the case get the smoking thing right. Of course, they banned smoking right after that.
I think with studios, it might not be that big of a deal if you are not close together especially with no children involved. However, if you have a 1 or 2 bedroom and studio and cooking will be involved, then closeness is a HUGE issue.
Good Luck!
