Yes, we do this very often! The most frequent deposits are 1BR SSR or OKW. I have seen BWI and AK. Don't waste your time looking for 2BR, because they rarely ever deposit those anymore. You can improve your chances by having an aged ongoing search in RCI and being very flexible with your dates. Right now there are lots of last minute deals (travel within 2 weeks) for a bargain if that works for you.
DVC generally deposits about 7 months in advance.
Do you have RCI points or weeks? I have weeks and it takes 50-55 TP for 1 DVC week, so you may need to combine your deposits to get to that. The last minute deals are 12-14 TP (one right now for 8/23 at SSR for 12 TP).
You can join Tuggs Forum and look at the Sightings and Distressed board for Disney to get an idea what people have gotten and to get a heads up on some of the last minute postings. They have lots of good advice on if what you want is likely to become available.
