...aaaaand perhaps a little love can go to SSR as well. The two major negatives for SSR are
- its layout is HUGE, HUGE I tells ya, and
- it's not close to any of the parks.
A minor minus
- the theme (upstate NY horse racing) is not as overwhelming as other, esp. Wilderness Lodge & Villas at Animal Kingdom Lodge
On the flip side, the rooms are very nice, it has two main pool areas and a smattering of smaller "quiet pools," its food court (Artist's Pallette) is IMO better organized than Good's Food to Go at OKW, I prefer the table service restaurant Turf Club over Olivia's @ OKW, and huge chunks of SSR are easily within walking distance of Downtown Disney. The Congress Park section especially. If you request that area (and the request is met), you'll be close to the Marketplace section of DtD, with all their shopping and dining options, PLUS you'll be close to the bus stop that takes people back to various WDW resorts. So if you have reservations for, say, Boma at Animal Kingdom Lodge one night for dinner, instead of taking a bus to the Animal Kingdom Park and transferring to the Lodge, you can just walk to the Marketplace and take one bus direct to the Lodge.
Having said that, I'm honestly not trying to sway your opinion, just wanted to point out that, indeed, all of the DVC resorts have things going for 'em.
Not knowing how many points you have available to you, though, I'd hazard to point to any one resort and say "THAT one. Go for THAT one." Because you're a family of 5 but two of the 5 are twins, I'm guessing you can opt to stay in any of the studio resorts, but that might be cramped for a family of 5, and you may want a little privacy from the rugrats (and they might want privacy from you) in which case a 1BR villa would make more sense, but again I don't know how many points you have at your disposal. If you can only get a studio, Old Key West are the largest, and the "Value" sized rooms at Animal Kingdom are the smallest, with Bay Lake Tower also being kinda teeny. If you can get a 1BR Villa, the ones at Bay Lake Tower, Kidani Village at Animl Kingdom Lodge and the Villas at Grand Floridian are the only ones to offer two bathrooms, all the other 1BR units only have 1 bathroom. When it comes to getting ready and getting out, not to mention coming back sometimes if anyone overate, having the extra bathroom could be a big big deal.
Other than that, like Weather_Lady wrote, it boils down to your preferences and what's available.
