We own at AKV and are staying at the Boardwalk this fall for the first time. We love AKV, the animals, the pool area, Kidani is a quick walk away, the Mara in Jambo house and no long hallways to walk down!
I'm also excited to stay at the Boardwalk, we will be there during food and wine and we can walk to two parks! So way less bus riding. We usually rent a car but we've decided not to this trip because of the easy walks from the boardwalk to Epcot and Hollywood Studios. The pool there doesn't excite me as much though and I'm worried about getting a room way far away from the lobby, but I think we will enjoy our time there.
Both resorts are great, you can't go wrong with either.
