Todd,
Thanks for asking your question to planDisney!
There are a lot of great choices for your adult-only getaway. You will want to consider location, based on what you plan on doing on this vacation, so that you are close to the magic that is important to you.
To begin, go to the Walt Disney World website and under "Places to Stay", select "Deluxe Villas". After you see the list of options appear, you can then enter your dates and it will give you an idea of what resort might already be fully booked. You will see that you have a lot of choices. I think it best to group them by location, and I have removed any that do not have two-bedroom villas or larger.
Magic Kingdom Area
These resorts are great for unique accommodations, great dining, and close access to the Magic Kingdom. The Bungalows at the Polynesian are an amazing over-the-water home with evening views of the fireworks from the park. The Copper Creek Cabins are equally unique, with a more serene and secluded setting. Any of the choices at these resorts should qualify in your top tier of options.
EPCOT Area
These resorts are great if you plan to dine 'around-the-world' in the EPCOT world showcase most nights. The Riviera is the newest of these, and the posh French theming might win out for elegance.
Animal Kingdom Area
These resorts are great but require bus rides to all the parks. Of the two parts of the Animal Kingdom resort with villas, I would opt for the Jambo house options.
Disney Springs Area
These are not the fanciest resorts at Walt Disney World, but if shopping and dining at the nearby Disney Springs is going to be a focal part of your trip, they are worth considering. I would lean towards Saratoga between the two.
I would suggest that the Magic Kingdom and EPCOT area resort choices are likely going to match what you are looking for, but certainly look through the options. I hope this helps. Write me back with more information if you need more advice.
Have a Magical Vacation!
