Vero Beach is nice too, I like it's away from WDW but still give you the Disney quailty. In WDW I like AKL the most because of the animals. I can't wait to try VGC, HHI and Ahlani. Wish they will build more DVC around the world.
My favorite is Bay Lake Tower. It offers the best view and has the most convenient transportation options compared to all the other DVC resorts. MK is just a short walk and it's very easy to access the monorail to Epcot and all the other resort hotels for breakfast and dinner. Watching fireworks from the room was also extra special.
Before BLT, I enjoyed Old Key West for the relaxing theming and large rooms. Only problem is I don't like relying solely on the bus system for transportation.
Boardwalk is good, too, for convenience. Lately, though, I've noticed that resort has been looking run down. Maybe they've already worked on it, but the carpeting in the hallyways were super worn.
