The two buildings themselves also offer a different "feel" to them as well as the room differences.
Jambo is closer to the "action". The resort lobby is big. Has many activities going on. Offers 3 dining options. It has a lot of life, energy and more fast-paced.
Kidani is more quiet, feels more secluded. The resort lobby is smaller, quiet. Only offers 1 dining option. It has a more relaxed feel.
