AKL had two different room sizes. The 4th floor and below have "standard" size rooms. Most of the 5th floor and all of the 6th floor had "deluxe" size rooms, about 40 square feet larger than the "standard" size rooms. There were also some "standard" size rooms on the 5th floor, located on both sides of the Giraffe and Ostrich trails (the two short trails along the front of the resort).
As already mentioned, when they convert AKL rooms into villas, they are using one AKL room to make a studio and two AKL rooms for a 1BR. Because there are both "standard" and "deluxe" size rooms on the 5th floor, the studios created from "deluxe" size rooms will be about 40 sq. ft. larger than the studios created from "standard" size rooms. The smaller studios (called "Value" studios) cost fewer points.
They are putting the kitchenette where the closet was in the AKL room. For lockoff studios, they are putting in an armoire instead of building a new closet. The dedicated studios do not have a connecting door to a 1BR, so they will have a closet where the connecting door would have been.
In the new building (Kidani Village) the studios will be about the same size as the larger studios in Jambo House.
