Well, it depends on which theme you like best. My preference is any part of WL, CCV and BRV, or the Cabins at FW. I have done several 3-4 night resort only stays there. But I live in Florida. Someone who lives in Wyoming or Colorado might prefer a tropical theme to a log cabin theme.
Personally, for a resort only stay I prefer to be in a resort that is not adjacent to the parks. So no monorail resorts and no Epcot resorts. For DVC that would leave OKW, SSR, RIV, AKV, and the wilderness properties. But that is just my preference. You might want to be where you can see fireworks easily or not mind seeing parks from a distance.
I would look at resort amenities, nearby dining options, and theme when making your choice.
CCV/BRV are good and calm and have decent access to other resorts. But I tend to navigate towards SSR because I like the easy access to DS and they never feel crowded.
Absolutely agree. Access to 2 pools, some of the best dining options on property (our opinion, of course!), some unique activities, and the animals. Such a peaceful and interesting place for a resort only stay.
