I haven't pool hopped, but I opted for your last option....variety of places.
Part of the appeal of DVC is not locking into one resort for 40 years. If you're going to go every year, might as well mix things up a little as far as where to stay. And amazingly, there are two more options (BCV and DIV) than when I joined six months ago!
Same philosophy with the pools. Part of upcoming vacations will include exploring areas of WDW we've never seen. That includes resorts, pools, attractions, whatever. We want to see it all (not on one trip!!).
This keeps every trip fresh and special in its own way.
Spice of life, and all that.
