Click here for a good site with photos of the
DVC resorts. Although this is a DVC info site, there are links on the left of the page that have photos of each resort.
This link is Disney's DVC link and if you scroll down the page you can "Explore" the resorts. Be sure to click on the "accomodations" link and "virtual tour" link to see floor plans and pictures.
I imagine your kids would LOVE the animals at AKV, especially if you get a savanah room. The pool is nice.
BWV has community hall (which you can use if you're staying at BCV), a nice pool and playground and the boardwalk itself.
BCV has a great pool.
OKW and SSR will most likely have rooms available at this late date for a January trip and each has great things for kids. SSR is newer and is close to DTD.
VWL has a good pool and great theming.
OKW, SSR, VWL have really good counter service locations for quick meals. BWV does not have a counter service location but it does have the bakery and a food cart (cash only, no dining plan), and a pizzeria on the boardwalk. BCV has on counter service location but it stays VERY busy and I'm not sure if it's open for breakfast.
We like BWV and VWL the best. We like the BWV (and BCV) b/c it is so close to EPCOT (within walking distance). I do miss having a counter service location, though, having kids.
