Others have posted that prime summer weeks at Massanutten (sp?), at least certain sections, will trade into DVC. Make sure that you are buying a prime summer week (26-31 is ideal with schools out, both north and south of there, a couple weeks on either side are good too) in one of the top sections.
Trading into 2BRs at DVC during the summer is difficult but not impossible if you're okay with OKW or SSR resorts. Place all the Orlando area Disneys (BCV, DAK, DBW, DSS, DVO, DWL) on your search request, at least 11 months ahead, up to 2 years out if you can, to get on the waitlist. Include as many check-in dates as possible. If you do all that, you'd likely match, IMO.
We have some NC and TX weeks that seem to trade extremely well in II but only decently well in RCI. Then we have a NC week that trades like a dog in II but acceptably in RCI. It's tough to know which will work best for a dual-affiliated resort until you try it for yourself. The hard thing is that my desired destinations will differ from yours. So what pleases me as a trade week may not please you. It's not always easy to know if a particular resort will be the tiger trader you'd like unless you are able to play with it for a while and see what it gets. Another thing that helps is to watch the sightings forum. If you frequently open the specific destinations that interest you most, and note what people are using to "see" them at RCI/II, that's a starting point. If they are not specific, you can email them and ask - they may or may not want to share this info but it's worth a try.
For the OP, you're wise to try to get a primetime week that you'd be pleased to use yourselves if trading doesn't pan out.

That's an excellent plan for a firsttime buyer. HTH!
