How long ago was that? We did something similar in 2014 (love love loved our week at Animal Kingdom, Kidani), but then Disney apparently changed the rules, and nowadays, almost the only thing that shows up for exchanges with RCI are 1 bedroom units, and those mostly at SSR.
I should also tell you that for the last 3 years, I have been on an RCI waiting list, asking to exchange into ANY 2 bedroom DVC unit, ANYWHERE in Disney World, and, on ANY dates. If anything opens up, I will make it happen, no matter when it falls. In addition, I paid RCI a $250 deposit (which they still have) to keep my search 'active.' And, guess what? In 3 years NO NIBBLES. (Oh, and I also have Worldmark Timeshare.) Essentially, that says that there must not have been ANY 2 bedroom DVC units available through RCI in the lst 3 years.
So, if you expect to trade into DVC with RCI, you will have a very limited number of units and a very poor selection and they will be at the less popular resorts and probably in 1 Bedrooms.
Disney has the right of first refusal on RCI trades, too. Meaning, if a DVC member goes to trade into RCI by giving up their DVC points, Disney almost always grabs those DVC points, rents out the unit for cash, and then it gives RCI some RCI points to compensate. At least that is how I understand it.
