All buildings at OKW have studios, one and two bedroom units. Make sure the two reservations have a "traveling with..." notation by calling Member Services. They will do their best to put you in the same or adjacent buildings, but it just depends upon what becomes available on your check-in day.
Whenever we've had multiple units, we have been in the same or adjacent buildings.
Also be sure both units are either booked as "Near Hospitality" or not, as "Near Hospitality" is a booking category at OKW.
