Wow, Stephanie! What a great opportunity! A stay at a Disney Vacation Club Studio at Walt Disney World! (You're going to love it, no matter which one you choose!)
Three DVC resorts you've selected are each truly fantastic; each one has its own personality, conveniences and Guest favorites, too. Once you've decided, I think that your best bet will be to ask more questions about that particular resort, too, so you don't miss a moment of the magic!
Consider if you'll be spending any time at one of Walt Disney World's parks; if so, which one. I suggest staying at
Disney's Animal Kingdom Villas-Kidani Village if you'll be visiting Disney's Animal Kingdom; stay at
The Villas at Disney's Wilderness Lodge if you'll be visiting Magic Kingdom. Should you be visiting Disney's Hollywood Studios or Epcot, consider
Disney's BoardWalk Villas. Each of the above-mentioned resorts are closest to the parks I've listed, and great proximity to at least one WDW park is a prime feature of these fabulous resorts!
If you'll spend a day or two at a resort each of these resorts have some great features for the little ones, too; so don't worry if any of them will be a spectacular stay for your family...each one would be!
Send another question, telling me if you have park plans either before or after your stay and I'll help direct you to the best option available. In the end, though, these are all special properties which are sure to impress!
