I would think if you've visited DSVII last time, you might want to try out the Shadow Ridge complex.
On the Villages side, you will get a traditional Marriott studio, but the Enclaves side has a couple of choices. They have a deluxe studio, which is also known as a "smaller one bedroom". In II, this is considered a one bedroom. It is the only Enclaves room configuration I haven't yet stayed in. As far as I can tell, it does not have the sliding wall, but an actual door into the bedroom. It looks a lot roomier than a traditional Marriott studio. I would try for this room type.
As others have mentioned, the traditional lock off/ studio on the Enclaves side has no balcony, thus making it avoidable for me.
But since your stay is only for a few nights, I think you'd be fine in any room. If you stay at the Shadow Ridge complex, make sure to explore in the whole thing. It is huge and each area has a different feel. Each pool area is also unique. I have stayed in all the MVCs in Palm Desert area and you can't go wrong with any of them. However, my family returns time and time again to Shadow Ridge because one pool area has a pool slide and that is the deciding factor for us!
Note: In DanaTom's description in post #3, read DSVI for II.
